LOCAL(8) LOCAL(8)
NAME
local - Postfix local mail delivery
SYNOPSIS
local [generic Postfix daemon options]
DESCRIPTION
The local(8) daemon processes delivery requests from the
Postfix queue manager to deliver mail to local recipients.
Each delivery request specifies a queue file, a sender
address, a domain or host to deliver to, and one or more
recipients. This program expects to be run from the mas-
ter(8) process manager.
The local(8) daemon updates queue files and marks recipi-
ents as finished, or it informs the queue manager that
delivery should be tried again at a later time. Delivery
status reports are sent to the bounce(8), defer(8) or
trace(8) daemon as appropriate.
CASE FOLDING
All delivery decisions are made using the bare recipient
name (i.e. the address localpart), folded to lower case.
See also under ADDRESS EXTENSION below for a few excep-
tions.
SYSTEM-WIDE AND USER-LEVEL ALIASING
The system administrator can set up one or more system-
wide sendmail-style alias databases. Users can have send-
mail-style ~/.forward files. Mail for name is delivered
to the alias name, to destinations in ~name/.forward, to
the mailbox owned by the user name, or it is sent back as
undeliverable.
The system administrator can specify a comma/space sepa-
rated list of ~/.forward like files through the for-
ward_path configuration parameter. Upon delivery, the
local delivery agent tries each pathname in the list until
a file is found.
Delivery via ~/.forward files is done with the privileges
of the recipient. Thus, ~/.forward like files must be
readable by the recipient, and their parent directory
needs to have "execute" permission for the recipient.
The forward_path parameter is subject to interpolation of
$user (recipient username), $home (recipient home direc-
tory), $shell (recipient shell), $recipient (complete
recipient address), $extension (recipient address exten-
sion), $domain (recipient domain), $local (entire recipi-
ent address localpart) and $recipient_delimiter. The forms
${name?value} and ${name:value} expand conditionally to
value when $name is (is not) defined. Characters that may
have special meaning to the shell or file system are
replaced by underscores. The list of acceptable charac-
ters is specified with the forward_expansion_filter con-
figuration parameter.
An alias or ~/.forward file may list any combination of
external commands, destination file names, :include:
directives, or mail addresses. See aliases(5) for a pre-
cise description. Each line in a user's .forward file has
the same syntax as the right-hand part of an alias.
When an address is found in its own alias expansion,
delivery is made to the user instead. When a user is
listed in the user's own ~/.forward file, delivery is made
to the user's mailbox instead. An empty ~/.forward file
means do not forward mail.
In order to prevent the mail system from using up unrea-
sonable amounts of memory, input records read from
:include: or from ~/.forward files are broken up into
chunks of length line_length_limit.
While expanding aliases, ~/.forward files, and so on, the
program attempts to avoid duplicate deliveries. The dupli-
cate_filter_limit configuration parameter limits the num-
ber of remembered recipients.
MAIL FORWARDING
For the sake of reliability, forwarded mail is re-submit-
ted as a new message, so that each recipient has a sepa-
rate on-file delivery status record.
In order to stop mail forwarding loops early, the software
adds an optional Delivered-To: header with the final enve-
lope recipient address. If mail arrives for a recipient
that is already listed in a Delivered-To: header, the mes-
sage is bounced.
MAILBOX DELIVERY
The default per-user mailbox is a file in the UNIX mail
spool directory (/var/mail/user or /var/spool/mail/user);
the location can be specified with the mail_spool_direc-
tory configuration parameter. Specify a name ending in /
for qmail-compatible maildir delivery.
Alternatively, the per-user mailbox can be a file in the
user's home directory with a name specified via the
home_mailbox configuration parameter. Specify a relative
path name. Specify a name ending in / for qmail-compatible
maildir delivery.
Mailbox delivery can be delegated to an external command
specified with the mailbox_command_maps and mailbox_com-
mand configuration parameters. The command executes with
the privileges of the recipient user (exceptions: sec-
ondary groups are not enabled; in case of delivery as
root, the command executes with the privileges of
default_privs).
Mailbox delivery can be delegated to alternative message
transports specified in the master.cf file. The mail-
box_transport_maps and mailbox_transport configuration
parameters specify an optional message transport that is
to be used for all local recipients, regardless of whether
they are found in the UNIX passwd database. The fall-
back_transport_maps and fallback_transport parameters
specify an optional message transport for recipients that
are not found in the aliases(5) or UNIX passwd database.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final envelope
recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines
beginning with "From ", and appends an empty line. The
mailbox is locked for exclusive access while delivery is
in progress. In case of problems, an attempt is made to
truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, prepends an X-Original-To: header with
the recipient address as given to Postfix, and prepends a
Return-Path: header with the envelope sender address.
EXTERNAL COMMAND DELIVERY
The allow_mail_to_commands configuration parameter
restricts delivery to external commands. The default set-
ting (alias, forward) forbids command destinations in
:include: files.
Optionally, the process working directory is changed to
the path specified with command_execution_directory (Post-
fix 2.2 and later). Failure to change directory causes
mail to be deferred.
The command_execution_directory parameter value is subject
to interpolation of $user (recipient username), $home
(recipient home directory), $shell (recipient shell),
$recipient (complete recipient address), $extension
(recipient address extension), $domain (recipient domain),
$local (entire recipient address localpart) and $recipi-
ent_delimiter. The forms ${name?value} and ${name:value}
expand conditionally to value when $name is (is not)
defined. Characters that may have special meaning to the
shell or file system are replaced by underscores. The
list of acceptable characters is specified with the execu-
tion_directory_expansion_filter configuration parameter.
The command is executed directly where possible. Assis-
tance by the shell (/bin/sh on UNIX systems) is used only
when the command contains shell magic characters, or when
the command invokes a shell built-in command.
A limited amount of command output (standard output and
standard error) is captured for inclusion with non-deliv-
ery status reports. A command is forcibly terminated if
it does not complete within command_time_limit seconds.
Command exit status codes are expected to follow the con-
ventions defined in <sysexits.h>. Exit status 0 means
normal successful completion.
Postfix version 2.3 and later support RFC 3463-style
enhanced status codes. If a command terminates with a
non-zero exit status, and the command output begins with
an enhanced status code, this status code takes precedence
over the non-zero exit status.
A limited amount of message context is exported via envi-
ronment variables. Characters that may have special mean-
ing to the shell are replaced by underscores. The list of
acceptable characters is specified with the command_expan-
sion_filter configuration parameter.
SHELL The recipient user's login shell.
HOME The recipient user's home directory.
USER The bare recipient name.
EXTENSION
The optional recipient address extension.
DOMAIN The recipient address domain part.
LOGNAME
The bare recipient name.
LOCAL The entire recipient address localpart (text to the
left of the rightmost @@ character).
ORIGINAL_RECIPIENT
The entire recipient address, before any address
rewriting or aliasing (Postfix 2.5 and later).
RECIPIENT
The entire recipient address.
SENDER The entire sender address.
Additional remote client information is made available via
the following environment variables:
CLIENT_ADDRESS
Remote client network address. Available as of
Postfix 2.2.
CLIENT_HELO
Remote client EHLO command parameter. Available as
of Postfix 2.2.
CLIENT_HOSTNAME
Remote client hostname. Available as of Postfix
2.2.
CLIENT_PROTOCOL
Remote client protocol. Available as of Postfix
2.2.
SASL_METHOD
SASL authentication method specified in the remote
client AUTH command. Available as of Postfix 2.2.
SASL_SENDER
SASL sender address specified in the remote client
MAIL FROM command. Available as of Postfix 2.2.
SASL_USERNAME
SASL username specified in the remote client AUTH
command. Available as of Postfix 2.2.
The PATH environment variable is always reset to a system-
dependent default path, and environment variables whose
names are blessed by the export_environment configuration
parameter are exported unchanged.
The current working directory is the mail queue directory.
The local(8) daemon prepends a "From sender time_stamp"
envelope header to each message, prepends an X-Original-
To: header with the recipient address as given to Postfix,
prepends an optional Delivered-To: header with the final
recipient envelope address, prepends a Return-Path: header
with the sender envelope address, and appends no empty
line.
EXTERNAL FILE DELIVERY
The delivery format depends on the destination filename
syntax. The default is to use UNIX-style mailbox format.
Specify a name ending in / for qmail-compatible maildir
delivery.
The allow_mail_to_files configuration parameter restricts
delivery to external files. The default setting (alias,
forward) forbids file destinations in :include: files.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final recipient
envelope address, prepends a > character to lines begin-
ning with "From ", and appends an empty line. The enve-
lope sender address is available in the Return-Path:
header. When the destination is a regular file, it is
locked for exclusive access while delivery is in progress.
In case of problems, an attempt is made to truncate a reg-
ular file to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, and prepends an X-Original-To: header
with the recipient address as given to Postfix. The enve-
lope sender address is available in the Return-Path:
header.
ADDRESS EXTENSION
The optional recipient_delimiter configuration parameter
specifies how to separate address extensions from local
recipient names.
For example, with "recipient_delimiter = +", mail for
name+foo is delivered to the alias name+foo or to the
alias name, to the destinations listed in ~name/.for-
ward+foo or in ~name/.forward, to the mailbox owned by the
user name, or it is sent back as undeliverable.
DELIVERY RIGHTS
Deliveries to external files and external commands are
made with the rights of the receiving user on whose behalf
the delivery is made. In the absence of a user context,
the local(8) daemon uses the owner rights of the :include:
file or alias database. When those files are owned by the
superuser, delivery is made with the rights specified with
the default_privs configuration parameter.
STANDARDS
RFC 822 (ARPA Internet Text Messages)
RFC 3463 (Enhanced status codes)
DIAGNOSTICS
Problems and transactions are logged to syslogd(8). Cor-
rupted message files are marked so that the queue manager
can move them to the corrupt queue afterwards.
Depending on the setting of the notify_classes parameter,
the postmaster is notified of bounces and of other trou-
ble.
SECURITY
The local(8) delivery agent needs a dual personality 1) to
access the private Postfix queue and IPC mechanisms, 2) to
impersonate the recipient and deliver to recipient-speci-
fied files or commands. It is therefore security sensi-
tive.
The local(8) delivery agent disallows regular expression
substitution of $1 etc. in alias_maps, because that would
open a security hole.
The local(8) delivery agent will silently ignore requests
to use the proxymap(8) server within alias_maps. Instead
it will open the table directly. Before Postfix version
2.2, the local(8) delivery agent will terminate with a
fatal error.
BUGS
For security reasons, the message delivery status of
external commands or of external files is never check-
pointed to file. As a result, the program may occasionally
deliver more than once to a command or external file. Bet-
ter safe than sorry.
Mutually-recursive aliases or ~/.forward files are not
detected early. The resulting mail forwarding loop is
broken by the use of the Delivered-To: message header.
CONFIGURATION PARAMETERS
Changes to main.cf are picked up automatically, as
local(8) processes run for only a limited amount of time.

@Import Postfix 2.8.1. Changes since version 2.7.*:
Postfix stable release 2.8.0 is available. This release continues the
move towards improving code and documentation, and making the system
better prepared for changes in the threat environment.
The postscreen daemon (a zombie blocker in front of Postfix) is now
included with the stable release. postscreen now supports TLS and can
log the rejected sender, recipient and helo information. See the
POSTSCREEN_README file for recommended usage scenarios.
Support for DNS whitelisting (permit_rhswl_client), and for pattern
matching to filter the responses from DNS white/blacklist servers
(e.g., reject_rhsbl_client zen.spamhaus.org=127.0.0.[1..10]).
Improved message tracking across SMTP-based content filters; the
after-filter SMTP server can log the before-filter queue ID (the
XCLIENT protocol was extended).
Read-only support for sqlite databases. See sqlite_table(5) and
SQLITE_README.
Support for 'footers' that are appended to SMTP server "reject"
responses. See "smtpd_reject_footer" in the postconf(5) manpage.

The local(8) daemon processes delivery requests from the Postfix queue
manager to deliver mail to local recipients. Each delivery request
specifies a queue file, a sender address, a domain or host to deliver
to, and one or more recipients. This program expects to be run from
the master(8) process manager.
The local(8) daemon updates queue files and marks recipients as fin-
ished, or it informs the queue manager that delivery should be tried
again at a later time. Delivery status reports are sent to the
bounce(8), defer(8) or trace(8) daemon as appropriate.
d30 4

All delivery decisions are made using the bare recipient name (i.e. the
address localpart), folded to lower case. See also under ADDRESS
EXTENSION below for a few exceptions.

The system administrator can set up one or more system-wide sendmail-
style alias databases. Users can have sendmail-style ~/.forward files.
Mail for name is delivered to the alias name, to destinations in
~name/.forward, to the mailbox owned by the user name, or it is sent
back as undeliverable.
The system administrator can specify a comma/space separated list of
~/.forward like files through the forward_path configuration parameter.
Upon delivery, the local delivery agent tries each pathname in the list
until a file is found.
Delivery via ~/.forward files is done with the privileges of the recip-
ient. Thus, ~/.forward like files must be readable by the recipient,
and their parent directory needs to have "execute" permission for the
recipient.
The forward_path parameter is subject to interpolation of $user (recip-
ient username), $home (recipient home directory), $shell (recipient
shell), $recipient (complete recipient address), $extension (recipient
address extension), $domain (recipient domain), $local (entire recipi-
ent address localpart) and $recipient_delimiter. The forms
${name?value} and ${name:value} expand conditionally to value when
$name is (is not) defined. Characters that may have special meaning to
the shell or file system are replaced by underscores. The list of
acceptable characters is specified with the forward_expansion_filter
configuration parameter.
An alias or ~/.forward file may list any combination of external com-
mands, destination file names, :include: directives, or mail addresses.
See aliases(5) for a precise description. Each line in a user's .for-
ward file has the same syntax as the right-hand part of an alias.
When an address is found in its own alias expansion, delivery is made
to the user instead. When a user is listed in the user's own ~/.forward
file, delivery is made to the user's mailbox instead. An empty ~/.for-
ward file means do not forward mail.
In order to prevent the mail system from using up unreasonable amounts
of memory, input records read from :include: or from ~/.forward files
are broken up into chunks of length line_length_limit.
While expanding aliases, ~/.forward files, and so on, the program
attempts to avoid duplicate deliveries. The duplicate_filter_limit con-
figuration parameter limits the number of remembered recipients.

For the sake of reliability, forwarded mail is re-submitted as a new
message, so that each recipient has a separate on-file delivery status
record.
In order to stop mail forwarding loops early, the software adds an
optional Delivered-To: header with the final envelope recipient
address. If mail arrives for a recipient that is already listed in a
Delivered-To: header, the message is bounced.

The default per-user mailbox is a file in the UNIX mail spool directory
(/var/mail/user or /var/spool/mail/user); the location can be specified
with the mail_spool_directory configuration parameter. Specify a name
ending in / for qmail-compatible maildir delivery.
Alternatively, the per-user mailbox can be a file in the user's home
directory with a name specified via the home_mailbox configuration
parameter. Specify a relative path name. Specify a name ending in / for
qmail-compatible maildir delivery.
Mailbox delivery can be delegated to an external command specified with
the mailbox_command_maps and mailbox_command configuration parameters.
The command executes with the privileges of the recipient user (excep-
tions: secondary groups are not enabled; in case of delivery as root,
the command executes with the privileges of default_privs).
Mailbox delivery can be delegated to alternative message transports
specified in the master.cf file. The mailbox_transport_maps and mail-
box_transport configuration parameters specify an optional message
transport that is to be used for all local recipients, regardless of
whether they are found in the UNIX passwd database. The fall-
back_transport_maps and fallback_transport parameters specify an
optional message transport for recipients that are not found in the
aliases(5) or UNIX passwd database.
In the case of UNIX-style mailbox delivery, the local(8) daemon
prepends a "From sender time_stamp" envelope header to each message,
prepends an X-Original-To: header with the recipient address as given
to Postfix, prepends an optional Delivered-To: header with the final
envelope recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines beginning with
"From ", and appends an empty line. The mailbox is locked for exclu-
sive access while delivery is in progress. In case of problems, an
attempt is made to truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends an optional
Delivered-To: header with the final envelope recipient address,
prepends an X-Original-To: header with the recipient address as given
to Postfix, and prepends a Return-Path: header with the envelope sender
address.
d150 34
a183 29
The allow_mail_to_commands configuration parameter restricts delivery
to external commands. The default setting (alias, forward) forbids com-
mand destinations in :include: files.
Optionally, the process working directory is changed to the path speci-
fied with command_execution_directory (Postfix 2.2 and later). Failure
to change directory causes mail to be deferred.
The command_execution_directory parameter value is subject to interpo-
lation of $user (recipient username), $home (recipient home directory),
$shell (recipient shell), $recipient (complete recipient address),
$extension (recipient address extension), $domain (recipient domain),
$local (entire recipient address localpart) and $recipient_delimiter.
The forms ${name?value} and ${name:value} expand conditionally to value
when $name is (is not) defined. Characters that may have special mean-
ing to the shell or file system are replaced by underscores. The list
of acceptable characters is specified with the execution_direc-
tory_expansion_filter configuration parameter.
The command is executed directly where possible. Assistance by the
shell (/bin/sh on UNIX systems) is used only when the command contains
shell magic characters, or when the command invokes a shell built-in
command.
A limited amount of command output (standard output and standard error)
is captured for inclusion with non-delivery status reports. A command
is forcibly terminated if it does not complete within com-
mand_time_limit seconds. Command exit status codes are expected to
follow the conventions defined in <sysexits.h>. Exit status 0 means

Postfix version 2.3 and later support RFC 3463-style enhanced status
codes. If a command terminates with a non-zero exit status, and the
command output begins with an enhanced status code, this status code
takes precedence over the non-zero exit status.
A limited amount of message context is exported via environment vari-
ables. Characters that may have special meaning to the shell are
replaced by underscores. The list of acceptable characters is speci-
fied with the command_expansion_filter configuration parameter.

to each message, prepends an X-Original-To: header with the recipient

The delivery format depends on the destination filename syntax. The
default is to use UNIX-style mailbox format. Specify a name ending in
/ for qmail-compatible maildir delivery.
The allow_mail_to_files configuration parameter restricts delivery to
external files. The default setting (alias, forward) forbids file des-
tinations in :include: files.
In the case of UNIX-style mailbox delivery, the local(8) daemon
prepends a "From sender time_stamp" envelope header to each message,
prepends an X-Original-To: header with the recipient address as given
to Postfix, prepends an optional Delivered-To: header with the final
recipient envelope address, prepends a > character to lines beginning
with "From ", and appends an empty line. The envelope sender address
is available in the Return-Path: header. When the destination is a
regular file, it is locked for exclusive access while delivery is in
progress. In case of problems, an attempt is made to truncate a regular
file to its original length.
In the case of maildir delivery, the local daemon prepends an optional
Delivered-To: header with the final envelope recipient address, and
prepends an X-Original-To: header with the recipient address as given
to Postfix. The envelope sender address is available in the Return-
Path: header.
d301 9
a309 7
The optional recipient_delimiter configuration parameter specifies how
to separate address extensions from local recipient names.
For example, with "recipient_delimiter = +", mail for name+foo is
delivered to the alias name+foo or to the alias name, to the destina-
tions listed in ~name/.forward+foo or in ~name/.forward, to the mailbox
owned by the user name, or it is sent back as undeliverable.
d312 6
a317 5
Deliveries to external files and external commands are made with the
rights of the receiving user on whose behalf the delivery is made. In
the absence of a user context, the local(8) daemon uses the owner
rights of the :include: file or alias database. When those files are
owned by the superuser, delivery is made with the rights specified with
d325 7

Problems and transactions are logged to syslogd(8). Corrupted message
files are marked so that the queue manager can move them to the corrupt
queue afterwards.
Depending on the setting of the notify_classes parameter, the postmas-
ter is notified of bounces and of other trouble.
d334 15
a348 12
The local(8) delivery agent needs a dual personality 1) to access the
private Postfix queue and IPC mechanisms, 2) to impersonate the recipi-
ent and deliver to recipient-specified files or commands. It is there-
fore security sensitive.
The local(8) delivery agent disallows regular expression substitution
of $1 etc. in alias_maps, because that would open a security hole.
The local(8) delivery agent will silently ignore requests to use the
proxymap(8) server within alias_maps. Instead it will open the table
directly. Before Postfix version 2.2, the local(8) delivery agent will
terminate with a fatal error.
d351 9
a359 8
For security reasons, the message delivery status of external commands
or of external files is never checkpointed to file. As a result, the
program may occasionally deliver more than once to a command or exter-
nal file. Better safe than sorry.
Mutually-recursive aliases or ~/.forward files are not detected early.
The resulting mail forwarding loop is broken by the use of the Deliv-
ered-To: message header.

to Postfix, prepends an optional Delivered-To: header with the final
envelope recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines beginning with
"From ", and appends an empty line. The mailbox is locked for exclu-
sive access while delivery is in progress. In case of problems, an
attempt is made to truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends an optional
Delivered-To: header with the final envelope recipient address,
prepends an X-Original-To: header with the recipient address as given
to Postfix, and prepends a Return-Path: header with the envelope sender
address.

The allow_mail_to_commands configuration parameter restricts delivery
to external commands. The default setting (alias, forward) forbids com-
mand destinations in :include: files.
Optionally, the process working directory is changed to the path speci-
fied with command_execution_directory (Postfix 2.2 and later). Failure
to change directory causes mail to be deferred.
The command_execution_directory parameter value is subject to interpo-
lation of $user (recipient username), $home (recipient home directory),
$shell (recipient shell), $recipient (complete recipient address),
$extension (recipient address extension), $domain (recipient domain),
$local (entire recipient address localpart) and $recipient_delimiter.
The forms ${name?value} and ${name:value} expand conditionally to value
when $name is (is not) defined. Characters that may have special mean-
ing to the shell or file system are replaced by underscores. The list
of acceptable characters is specified with the execution_direc-
tory_expansion_filter configuration parameter.
The command is executed directly where possible. Assistance by the
shell (/bin/sh on UNIX systems) is used only when the command contains
shell magic characters, or when the command invokes a shell built-in
command.
A limited amount of command output (standard output and standard error)
is captured for inclusion with non-delivery status reports. A command
is forcibly terminated if it does not complete within com-
mand_time_limit seconds. Command exit status codes are expected to
follow the conventions defined in <sysexits.h>. Exit status 0 means

Postfix version 2.3 and later support RFC 3463-style enhanced status
codes. If a command terminates with a non-zero exit status, and the
command output begins with an enhanced status code, this status code
takes precedence over the non-zero exit status.
A limited amount of message context is exported via environment vari-
ables. Characters that may have special meaning to the shell are
replaced by underscores. The list of acceptable characters is speci-

The delivery format depends on the destination filename syntax. The
default is to use UNIX-style mailbox format. Specify a name ending in

In the case of UNIX-style mailbox delivery, the local(8) daemon
prepends a "From sender time_stamp" envelope header to each message,
prepends an X-Original-To: header with the recipient address as given

is available in the Return-Path: header. When the destination is a
regular file, it is locked for exclusive access while delivery is in
progress. In case of problems, an attempt is made to truncate a regular
file to its original length.
In the case of maildir delivery, the local daemon prepends an optional

The optional recipient_delimiter configuration parameter specifies how
to separate address extensions from local recipient names.
For example, with "recipient_delimiter = +", mail for name+foo is
delivered to the alias name+foo or to the alias name, to the destina-
tions listed in ~name/.forward+foo or in ~name/.forward, to the mailbox
owned by the user name, or it is sent back as undeliverable.

Deliveries to external files and external commands are made with the
rights of the receiving user on whose behalf the delivery is made. In
the absence of a user context, the local(8) daemon uses the owner
rights of the :include: file or alias database. When those files are
owned by the superuser, delivery is made with the rights specified with

Problems and transactions are logged to syslogd(8). Corrupted message

The local(8) delivery agent needs a dual personality 1) to access the
private Postfix queue and IPC mechanisms, 2) to impersonate the recipi-
ent and deliver to recipient-specified files or commands. It is there-
fore security sensitive.
The local(8) delivery agent disallows regular expression substitution
of $1 etc. in alias_maps, because that would open a security hole.
The local(8) delivery agent will silently ignore requests to use the
proxymap(8) server within alias_maps. Instead it will open the table
directly. Before Postfix version 2.2, the local(8) delivery agent will
terminate with a fatal error.
d351 9
a359 8
For security reasons, the message delivery status of external commands
or of external files is never checkpointed to file. As a result, the
program may occasionally deliver more than once to a command or exter-
nal file. Better safe than sorry.
Mutually-recursive aliases or ~/.forward files are not detected early.
The resulting mail forwarding loop is broken by the use of the Deliv-
ered-To: message header.

@Import Postfix 2.11.1. The main changes since version 2.10.* are:
- Support for PKI-less TLS server certificate verification with DANE
(DNS-based Authentication of Named Entities) where the CA public key
or the server certificate is identified via DNSSEC lookup. This
requires a DNS resolver that validates DNSSEC replies. The problem
with conventional PKI is that there are literally hundreds of
organizations world-wide that can provide a certificate in anyone's
name. DANE limits trust to the people who control the target DNS
zone and its parent zones.
- A new postscreen_dnsbl_whitelist_threshold feature to allow clients
to skip postscreen tests based on their DNSBL score. This can
eliminate email delays due to "after 220 greeting" protocol tests,
which otherwise require that a client reconnects before it can
deliver mail. Some providers such as Google don't retry from the
same IP address, and that can result in large email delivery delays.
- The recipient_delimiter feature now supports different delimiters,
for example both "+" and "-". As before, this implementation
recognizes exactly one delimiter character per email address, and
exactly one address extension per email address.
- Advanced master.cf query/update support to access service attributes
as "name = value" pairs. For example to turn off chroot on all
services use "postconf -F '*/*/chroot = n'", and to change/add a
"-o name=value" setting use "postconf -P 'smtp/inet/name = value'".
This was developed primarily to allow automated tools to manage Postfix
systems without having to parse Postfix configuration files.

The local(8) daemon processes delivery requests from the Postfix queue
manager to deliver mail to local recipients. Each delivery request
specifies a queue file, a sender address, a domain or host to deliver
to, and one or more recipients. This program expects to be run from
the master(8) process manager.
The local(8) daemon updates queue files and marks recipients as fin-
ished, or it informs the queue manager that delivery should be tried
again at a later time. Delivery status reports are sent to the
bounce(8), defer(8) or trace(8) daemon as appropriate.
d30 4
a33 3
All delivery decisions are made using the bare recipient name (i.e. the
address localpart), folded to lower case. See also under ADDRESS
EXTENSION below for a few exceptions.
d36 52
a87 44
The system administrator can set up one or more system-wide sendmail-
style alias databases. Users can have sendmail-style ~/.forward files.
Mail for name is delivered to the alias name, to destinations in
~name/.forward, to the mailbox owned by the user name, or it is sent
back as undeliverable.
The system administrator can specify a comma/space separated list of
~/.forward like files through the forward_path configuration parameter.
Upon delivery, the local delivery agent tries each pathname in the list
until a file is found.
Delivery via ~/.forward files is done with the privileges of the recip-
ient. Thus, ~/.forward like files must be readable by the recipient,
and their parent directory needs to have "execute" permission for the
recipient.
The forward_path parameter is subject to interpolation of $user (recip-
ient username), $home (recipient home directory), $shell (recipient
shell), $recipient (complete recipient address), $extension (recipient
address extension), $domain (recipient domain), $local (entire recipi-
ent address localpart) and $recipient_delimiter. The forms
${name?value} and ${name:value} expand conditionally to value when
$name is (is not) defined. Characters that may have special meaning to
the shell or file system are replaced by underscores. The list of
acceptable characters is specified with the forward_expansion_filter
configuration parameter.
An alias or ~/.forward file may list any combination of external com-
mands, destination file names, :include: directives, or mail addresses.
See aliases(5) for a precise description. Each line in a user's .for-
ward file has the same syntax as the right-hand part of an alias.
When an address is found in its own alias expansion, delivery is made
to the user instead. When a user is listed in the user's own ~/.forward
file, delivery is made to the user's mailbox instead. An empty ~/.for-
ward file means do not forward mail.
In order to prevent the mail system from using up unreasonable amounts
of memory, input records read from :include: or from ~/.forward files
are broken up into chunks of length line_length_limit.
While expanding aliases, ~/.forward files, and so on, the program
attempts to avoid duplicate deliveries. The duplicate_filter_limit con-
figuration parameter limits the number of remembered recipients.
d90 9
a98 8
For the sake of reliability, forwarded mail is re-submitted as a new
message, so that each recipient has a separate on-file delivery status
record.
In order to stop mail forwarding loops early, the software adds an
optional Delivered-To: header with the final envelope recipient
address. If mail arrives for a recipient that is already listed in a
Delivered-To: header, the message is bounced.
d101 47

The default per-user mailbox is a file in the UNIX mail spool directory
(/var/mail/user or /var/spool/mail/user); the location can be specified
with the mail_spool_directory configuration parameter. Specify a name
ending in / for qmail-compatible maildir delivery.
Alternatively, the per-user mailbox can be a file in the user's home
directory with a name specified via the home_mailbox configuration
parameter. Specify a relative path name. Specify a name ending in / for
qmail-compatible maildir delivery.
Mailbox delivery can be delegated to an external command specified with
the mailbox_command_maps and mailbox_command configuration parameters.
The command executes with the privileges of the recipient user (excep-
tions: secondary groups are not enabled; in case of delivery as root,
the command executes with the privileges of default_privs).
Mailbox delivery can be delegated to alternative message transports
specified in the master.cf file. The mailbox_transport_maps and mail-
box_transport configuration parameters specify an optional message
transport that is to be used for all local recipients, regardless of
whether they are found in the UNIX passwd database. The fall-
back_transport_maps and fallback_transport parameters specify an
optional message transport for recipients that are not found in the
aliases(5) or UNIX passwd database.
In the case of UNIX-style mailbox delivery, the local(8) daemon
prepends a "From sender time_stamp" envelope header to each message,
prepends an X-Original-To: header with the recipient address as given
to Postfix, prepends an optional Delivered-To: header with the final
envelope recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines beginning with
"From ", and appends an empty line. The mailbox is locked for exclu-
sive access while delivery is in progress. In case of problems, an
attempt is made to truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends an optional
Delivered-To: header with the final envelope recipient address,
prepends an X-Original-To: header with the recipient address as given
to Postfix, and prepends a Return-Path: header with the envelope sender
address.

Optionally, the process working directory is changed to the path speci-
fied with command_execution_directory (Postfix 2.2 and later). Failure
to change directory causes mail to be deferred.
The command_execution_directory parameter value is subject to interpo-

The local(8) delivery agent needs a dual personality 1) to access the
private Postfix queue and IPC mechanisms, 2) to impersonate the recipi-
ent and deliver to recipient-specified files or commands. It is there-
fore security sensitive.
The local(8) delivery agent disallows regular expression substitution
of $1 etc. in alias_maps, because that would open a security hole.
The local(8) delivery agent will silently ignore requests to use the
proxymap(8) server within alias_maps. Instead it will open the table
directly. Before Postfix version 2.2, the local(8) delivery agent will
terminate with a fatal error.

For security reasons, the message delivery status of external commands
or of external files is never checkpointed to file. As a result, the
program may occasionally deliver more than once to a command or exter-
nal file. Better safe than sorry.
Mutually-recursive aliases or ~/.forward files are not detected early.
The resulting mail forwarding loop is broken by the use of the Deliv-
ered-To: message header.

@The stable Postfix release is called postfix-3.0.x where 3=major
release number, 0=minor release number, x=patchlevel. The stable
release never changes except for patches that address bugs or
emergencies. Patches change the patchlevel and the release date.
New features are developed in snapshot releases. These are called
postfix-3.1-yyyymmdd where yyyymmdd is the release date (yyyy=year,
mm=month, dd=day). Patches are never issued for snapshot releases;
instead, a new snapshot is released.
The mail_release_date configuration parameter (format: yyyymmdd)
specifies the release date of a stable release or snapshot release.
If you upgrade from Postfix 2.10 or earlier, read RELEASE_NOTES-2.11
before proceeding.
Notes for distribution maintainers
----------------------------------
* New backwards-compatibility safety net.
With NEW Postfix installs, you MUST install a main.cf file with
the setting "compatibility_level = 2". See conf/main.cf for an
example.
With UPGRADES of existing Postfix systems, you MUST NOT change the
main.cf compatibility_level setting, nor add this setting if it
does not exist.
Several Postfix default settings have changed with Postfix 3.0. To
avoid massive frustration with existing Postfix installations,
Postfix 3.0 comes with a safety net that forces Postfix to keep
running with backwards-compatible main.cf and master.cf default
settings. This safety net depends on the main.cf compatibility_level
setting (default: 0). Details are in COMPATIBILITY_README.
* New Postfix build system.
The Postfix build/install procedure has changed to support Postfix
dynamically-linked libraries and database plugins. These must not
be "shared" with non-Postfix programs, and therefore must not be
installed in a public directory.
To avoid massive frustration due to broken patches, PLEASE BUILD
POSTFIX FIRST WITHOUT APPLYING ANY PATCHES. Follow the INSTALL
instructions (see "Building with Postfix dynamically-linked libraries
and database plugins"), and see how things work and what the
dynamically-linked libraries, database plugin, and configuration
files look like. Then, go ahead and perform your platform-specific
customizations. The INSTALL section "Tips for distribution maintainers"
has further suggestions.
Major changes - critical
------------------------
[Incompat 20140714] After upgrading Postfix, "postfix reload" (or
start/stop) is required. Several Postfix-internal protocols have
been extended to support SMTPUTF8. Failure to reload or restart
will result in mail staying queued, while Postfix daemons log
warning messages about unexpected attributes.
Major changes - default settings
--------------------------------
[Incompat 20141009] The default settings have changed for relay_domains
(new: empty, old: $mydestination) and mynetworks_style (new: host,
old: subnet). However the backwards-compatibility safety net will
prevent these changes from taking effect, giving the system
administrator the option to make an old default setting permanent
in main.cf or to adopt the new default setting, before turning off
backwards compatibility. See COMPATIBILITY_README for details.
[Incompat 20141001] A new backwards-compatibility safety net forces
Postfix to run with backwards-compatible main.cf and master.cf
default settings after an upgrade to a newer but incompatible Postfix
version. See COMPATIBILITY_README for details.
While the backwards-compatible default settings are in effect,
Postfix logs what services or what email would be affected by the
incompatible change. Based on this the administrator can make some
backwards-compatibility settings permanent in main.cf or master.cf,
before turning off backwards compatibility.
See postconf.5.html#compatibility_level for details.
[Incompat 20141001] The default settings
have changed for append_dot_mydomain (new: no. old: yes), master.cf
chroot (new: n, old: y), and smtputf8 (new: yes, old: no).
Major changes - access control
------------------------------
[Feature 20141119] Support for BCC actions in header/body_checks
and milter_header_checks. There is no limit on the number of BCC
actions that may be specified, other than the implicit limit due
to finite storage. BCC support will not be implemented in Postfix
delivery agent header/body_checks.
It works in the same way as always_bcc and sender/recipient_bcc_maps:
there can be only one address per action, recipients are added with
the NOTIFY=NONE delivery status notification option, and duplicate
recipients are ignored (with the same delivery status notification
options).
[Incompat 20141009] The default settings have changed for relay_domains
(new: empty, old: $mydestination) and mynetworks_style (new: host,
old: subnet). However the backwards-compatibility safety net will
prevent these changes from taking effect, giving the system
administrator the option to make an old default setting permanent
in main.cf or to adopt the new default setting, before turning off
backwards compatibility. See COMPATIBILITY_README for details.
[Feature 20140618] New INFO action in access(5) tables, for consistency
with header/body_checks.
[Feature 20140620] New check_xxx_a_access (for xxx in client,
reverse_client, helo, sender, recipient) implements access control
on all A and AAAA IP addresses for respectively the client hostname,
helo parameter, sender domain or recipient domain. This complements
the existing check_xxx_mx_access and check_xxx_ns_access features.
Major changes - address rewriting
---------------------------------
[Incompat 20141001] The default settings have changed for
append_dot_mydomain (new: no. old: yes), master.cf chroot (new:
n, old: y), and smtputf8 (new: yes, old: no).
Major changes - address verification
------------------------------------
[Feature 20141227] The new smtp_address_verify_target parameter
(default: rcpt) specifies what protocol stage decides if a recipient
is valid. Specify "data" for servers that reject invalid recipients
in response to the DATA command.
Major changes - database support
--------------------------------
[Feature 20140512] Support for Berkeley DB version 6.
[Feature 20140618] The "randmap" lookup table performs random
selection. This may be used to implement load balancing, for example:
/etc/postfix/transport:
# Deliver my own domain as usual.
example.com :
.example.com :
/etc/postfix/main.cf:
transport_maps =
# Deliver my own domain as usual.
hash:/etc/postfix/transport
# Deliver other domains via randomly-selected relayhosts
randmap:{smtp:smtp0.example.com, smtp:smtp1.example.com}
A variant of this can randomly select SMTP clients with different
smtp_bind_address settings.
To implement different weights, specify lookup results multiple
times. For example, to choose smtp:smtp1.example.com twice as often
as smtp:smtp0.example.com, specify smtp:smtp1.example.com twice.
A future version may support randmap:/path/to/file to load a list
of results from file.
[Feature 20140618] As the name suggests, the "pipemap" table
implements a pipeline of lookup tables. The name of the table
specifies the pipeline as a sequence of tables. For example, the
following prevents SMTP mail to system accounts that have "nologin"
as their login shell:
/etc/postfix/main.cf:
local_recipient_maps =
pipemap:{unix:passwd.byname, pcre:/etc/postfix/no-nologin.pcre}
alias_maps
/etc/postfix/no-nologin.pcre:
!/nologin/ whatever
Each "pipemap:" query is given to the first table. Each table
lookup result becomes the query for the next table in the pipeline,
and the last table produces the final result. When any table lookup
produces no result, the entire pipeline produces no result.
A future version may support pipemap:/path/to/file to load a list
of lookup tables from file.
[Feature 20140924] Support for unionmap, with the same syntax as
pipemap. This sends a query to all tables, and concatenates non-empty
results, separated by comma.
[Feature 20131121] The "static" lookup table now supports whitespace
when invoked as "static:{ text with whitespace }", so that it can
be used, for example, at the end of smtpd_mumble_restrictions as
"check_mumble_access static:{reject text...}".
[Feature 20141126] "inline:{key=value, { key = text with comma/space}}"
avoids the need to create a database for just a few entries.
Major changes - delivery status notifications
---------------------------------------------
[Feature 20140321] Delivery status filter support, to replace the
delivery status codes and explanatory text of successful or
unsuccessful deliveries by Postfix mail delivery agents.
This was originally implemented for sites that want to turn certain
soft delivery errors into hard delivery errors, but it can also be
used to censor out information from delivery confirmation reports.
This feature is implemented as a filter that replaces the three-number
enhanced status code and descriptive text in Postfix delivery agent
success, bounce, or defer messages. Note: this will not override
"soft_bounce=yes", and this will not change a successful delivery
status into an unsuccessful status or vice versa.
The first example turns specific soft TLS errors into hard
errors, by overriding the first number in the enhanced status code.
/etc/postfix/main.cf:
smtp_delivery_status_filter = pcre:/etc/postfix/smtp_dsn_filter
/etc/postfix/smtp_dsn_filter:
/^4(\.\d+\.\d+ TLS is required, but host \S+ refused to start TLS: .+)/ 5$1
/^4(\.\d+\.\d+ TLS is required, but was not offered by host .+)/ 5$1
The second example removes the destination command name and file
name from local(8) successful delivery reports, so that they will
not be reported when a sender requests confirmation of delivery.
/etc/postfix/main.cf:
local_delivery_status_filter = pcre:/etc/postfix/local_dsn_filter
/etc/postfix/local_dsn_filter:
/^(2\S+ delivered to file).+/ $1
/^(2\S+ delivered to command).+/ $1
This feature is supported in the lmtp(8), local(8), pipe(8), smtp(8)
and virtual(8) delivery agents. That is, all delivery agents that
actually deliver mail. It will not be implemented in the error and
retry pseudo-delivery agents.
The new main.cf parameters and default values are:
default_delivery_status_filter =
lmtp_delivery_status_filter = $default_delivery_status_filter
local_delivery_status_filter = $default_delivery_status_filter
pipe_delivery_status_filter = $default_delivery_status_filter
smtp_delivery_status_filter = $default_delivery_status_filter
virtual_delivery_status_filter = $default_delivery_status_filter
See the postconf(5) manpage for more details.
[Incompat 20140618] The pipe(8) delivery agent will now log a limited
amount of command output upon successful delivery, and will report
that output in "SUCCESS" delivery status reports. This is another
good reason to disable inbound DSN requests at the Internet perimeter.
[Feature 20140907] With "confirm_delay_cleared = yes", Postfix
informs the sender when delayed mail leaves the queue (this is in
addition to the delay_warning_time feature that warns when mail is
still queued). This feature is disabled by default, because it can
result in a sudden burst of notifications when the queue drains at
the end of a prolonged network outage.
Major changes - dns
-------------------
[Feature 20141128] Support for DNS server reply filters in the
Postfix SMTP/LMTP client and SMTP server. This helps to work around
mail delivery problems with sites that have incorrect DNS information.
Note: this has no effect on the implicit DNS lookups that are made
by nsswitch.conf or equivalent mechanisms.
This feature renders each lookup result as one line of text in
standard zone-file format as shown below. The class field is always
"IN", the preference field exists only for MX records, the names
of hosts, domains, etc. end in ".", and those names are in ASCII
form (xn--mumble form for internationalized domain names).
name ttl class type preference value
---------------------------------------------------------
postfix.org. 86400 IN MX 10 mail.cloud9.net.
Typically, one would match this text with a regexp: or pcre: table.
When a match is found, the table lookup result specifies an action.
By default, the table query and the action name are case-insensitive.
Currently, only the IGNORE action is implemented.
For safety reasons, Postfix logs a warning or defers mail delivery
when a DNS reply filter removes all lookup results from a successful
query.
The Postfix SMTP/LMTP client uses the smtp_dns_reply_filter and
lmtp_dns_reply_filter features only for Postfix SMTP client lookups
of MX, A, and AAAAA records to locate a remote SMTP or LMTP server,
including lookups that implement the features reject_unverified_sender
and reject_unverified_recipient. The filters are not used for lookups
made through nsswitch.conf and similar mechanisms.
The Postfix SMTP server uses the smtpd_dns_reply_filter feature
only for Postfix SMTP server lookups of MX, A, AAAAA, and TXT records
to implement the features reject_unknown_helo_hostname,
reject_unknown_sender_domain, reject_unknown_recipient_domain,
reject_rbl_*, and reject_rhsbl_*. The filter is not used for lookups
made through nsswitch.conf and similar mechanisms, such as lookups
of the remote SMTP client name.
[Feature 20141126] Nullmx support (MX records with a null hostname).
This change affects error messages only. The Postfix SMTP client
already bounced mail for such domains, and the Postfix SMTP server
already rejected such domains with reject_unknown_sender/recipient_domain.
This feature introduces a new SMTP server configuration parameter
nullmx_reject_code (default: 556).
Major changes - dynamic linking
-------------------------------
[Feature 20140530] Support to build Postfix with Postfix
dynamically-linked libraries, and with dynamically-loadable database
clients. These MUST NOT be used by non-Postfix programs. Postfix
dynamically-linked libraries introduce minor runtime overhead and
result in smaller Postfix executable files. Dynamically-loadable
database clients are useful when you distribute or install pre-compiled
packages. Postfix 3.0 supports dynamic loading for CDB, LDAP, LMDB,
MYSQL, PCRE, PGSQL, SDBM, and SQLITE database clients.
This implementation is based on Debian code by LaMont Jones, initially
ported by Viktor Dukhovni. Currently, support exists for recent
versions of Linux, FreeBSD, MacOS X, and for the ancient Solaris 9.
To support Postfix dynamically-linked libraries and dynamically-loadable
database clients, the Postfix build procedure had to be changed
(specifically, the files makedefs and Makefile.in, and the files
postfix-install and post-install that install or update Postfix).
[Incompat 20140530] The Postfix 3.0 build procedure expects that
you specify database library dependencies with variables named
AUXLIBS_CDB, AUXLIBS_LDAP, etc. With Postfix 3.0 and later, the
old AUXLIBS variable still supports building a statically-loaded
CDB etc. database client, but only the new AUXLIBS_CDB etc. variables
support building a dynamically-loaded or statically-loaded CDB etc.
database client. See CDB_README, LDAP_README, etc. for details.
Failure to follow this advice will defeat the purpose of dynamic
database client loading. Every Postfix executable file will have
database library dependencies. And that was exactly what dynamic
database client loading was meant to avoid.
Major changes - future proofing
-------------------------------
[Cleanup 20141224] The changes described here have no visible effect
on Postfix behavior, but they make Postfix code easier to maintain,
and therefore make new functionality easier to add.
* Compile-time argument typechecks of non-printf/scanf-like variadic
function argument lists.
* Deprecating the use of "char *" for non-text purposes such as
memory allocation and pointers to application context for call-back
functions. This dates from long-past days before void * became
universally available.
* Replace integer types for counters and sizes with size_t or ssize_t
equivalents. This eliminates some wasteful 64<->32bit conversions
on 64-bit systems.
Major changes - installation pathnames
--------------------------------------
[Incompat 20140625] For compliance with file system policies, some
non-executable files have been moved from $daemon_directory to the
directory specified with the new meta_directory configuration
parameter which has the same default value as the config_directory
parameter. This change affects non-executable files that are shared
between multiple Postfix instances such as postfix-files, dynamicmaps.cf,
and multi-instance template files.
For backwards compatibility with Postfix 2.6 .. 2.11, specify
"meta_directory = $daemon_directory" in main.cf before installing
or upgrading Postfix, or specify "meta_directory = /path/name" on
the "make makefiles", "make install" or "make upgrade" command line.
Major changes - milter
----------------------
[Feature 20140928] Support for per-Milter settings that override
main.cf parameters. For details see the section "Advanced policy
client configuration" in the SMTPD_POLICY_README document.
Here is an example that uses both old and new syntax:
smtpd_milters = { inet:127.0.0.1:port1, default_action=accept, ... },
inet:127.0.0.1:port2, ...
The supported attribute names are: command_timeout, connect_timeout,
content_timeout, default_action, and protocol. These have the same
names as the corresponding main.cf parameters, without the "milter_"
prefix.
The per-milter settings are specified as attribute=value pairs
separated by comma or space; specify { name = value } to allow
spaces around the "=" or within an attribute value.
[Feature 20141018] DMARC compatibility: when a Milter inserts a
header ABOVE Postfix's own Received: header, Postfix no longer
exposes its own Received: header to Milters (violating protocol)
and Postfix no longer hides the Milter-inserted header from Milters
(wtf).
Major changes - parameter syntax
--------------------------------
[Feature 20140921] In preparation for configurable mail headers and
logging, new main.cf support for if-then-else expressions:
${name?{text1}:{text2}}
and for logical expressions:
${{text1}=={text2}?{text3}:{text4}}
${{text1}!={text2}?{text3}:{text4}}
Whitespace before and after {text} is ignored. This can help to
make complex expressions more readable. See the postconf(5) manpage
for further details.
[Feature 20140928] Support for whitespace in daemon command-line
arguments. For details, see the "Command name + arguments" section
in the master(5) manpage. Example:
smtpd -o { parameter = value containing whitespace } ...
The { ... } form is also available for non-option command-line
arguments in master.cf, for example:
pipe ... argv=command { argument containing whitespace } ...
In both cases, whitespace immediately after "{" and before "}"
is ignored.
[Feature 20141005] Postfix import_environment and export_environment
now allow "{ name=value }" to protect whitespace in attribute values.
[Feature 20141006] The new message_drop_header parameter replaces
a hard-coded table that specifies what message headers the cleanup
daemon will remove. The list of supported header names covers RFC
5321, 5322, MIME RFCs, and some historical names.
Major changes - pipe daemon
---------------------------
[Incompat 20140618] The pipe(8) delivery agent will now log a limited
amount of command output upon successful delivery, and will report
that output in "SUCCESS" delivery status reports. This is another
good reason to disable inbound DSN requests at the Internet perimeter.
Major changes - policy client
-----------------------------
[Feature 20140703] This release introduces three new configuration
parameters that control error recovery for failed SMTPD policy
requests.
* smtpd_policy_service_default_action (default: 451 4.3.5 Server
configuration problem): The default action when an SMTPD policy
service request fails.
* smtpd_policy_service_try_limit (default: 2): The maximal number
of attempts to send an SMTPD policy service request before
giving up. This must be a number greater than zero.
* smtpd_policy_service_retry_delay (default: 1s): The delay between
attempts to resend a failed SMTPD policy service request. This
must be a number greater than zero.
See postconf(5) for details and limitations.
[Feature 20140928] Support for per-policy service settings that
override main.cf parameters. For details see the section "Different
settings for different Milter applications" in the MILTER_README
document.
Here is an example that uses both old and new syntax:
smtpd_recipient_restrictions = ...
check_policy_service { inet:127.0.0.1:port3, default_action=DUNNO }
check_policy_service inet:127.0.0.1:port4
...
The per-policy service settings are specified as attribute=value pairs
separated by comma or space; specify { name = value } to allow
spaces around the "=" or within an attribute value.
The supported attribute names are: default_action, max_idle, max_ttl,
request_limit, retry_delay, timeout, try_limit. These have the same
names as the corresponding main.cf parameters, without the
"smtpd_policy_service_" prefix.
[Feature 20140505] A client port attribute was added to the policy
delegation protocol.
[Feature 20140630] New smtpd_policy_service_request_limit feature to
limit the number of requests per Postfix SMTP server policy connection.
This is a workaround to avoid error-recovery delays with policy
servers that cannot maintain a persistent connection.
Major changes - position-independent executables
------------------------------------------------
[Feature 20150205] Preliminary support for building position-independent
executables (PIE), tested on Fedora Core 20, Ubuntu 14.04, FreeBSD
9 and 10, and NetBSD 6. Specify:
$ make makefiles pie=yes ...other arguments...
On some systems, PIE is used by the ASLR exploit mitigation technique
(ASLR = Address-Space Layout Randomization). Whether specifying
"pie=yes" has any effect at all depends on the compiler. Reportedly,
some compilers always produce PIE executables.
Major changes - postscreen
--------------------------
[Feature 20140501] Configurable time limit (postscreen_dnsbl_timeout)
for DNSBL or DNSWL lookups. This is separate from the timeouts in
the dnsblog(8) daemon which are controlled by system resolver(3)
routines.
Major changes - session fingerprint
-----------------------------------
[Feature 20140801] The Postfix SMTP server now logs at the end of
a session how many times an SMTP command was successfully invoked,
followed by the total number of invocations if some invocations
were unsuccessful.
This logging will enough to diagnose many problems without using
verbose logging or network sniffer.
Normal session, no TLS:
disconnect from name[addr] ehlo=1 mail=1 rcpt=1 data=1 quit=1
Normal session. with TLS:
disconnect from name[addr] ehlo=2 starttls=1 mail=1 rcpt=1 data=1 quit=1
All recipients rejected, no ESMTP command pipelining:
disconnect from name[addr] ehlo=1 mail=1 rcpt=0/1 quit=1
All recipients rejected, with ESMTP command pipelining:
disconnect from name[addr] ehlo=1 mail=1 rcpt=0/1 data=0/1 rset=1 quit=1
Password guessing bot, hangs up without QUIT:
disconnect from name[addr] ehlo=1 auth=0/1
Mis-configured client trying to use TLS wrappermode on port 587:
disconnect from name[addr] unknown=0/1
Logfile analyzers can trigger on the presence of "/". It indicates
that Postfix rejected at least one command.
[Feature 20150118] As a late addition, the SMTP server now also
logs the total number of commands (as "commands=x/y") even when the
client did not send any commands. This helps logfile analyzers to
recognize sessions without commands.
Major changes - smtp client
---------------------------
[Feature 20141227] The new smtp_address_verify_target parameter
(default: rcpt) determines what protocol stage decides if a recipient
is valid. Specify "data" for servers that reject recipients after
the DATA command.
Major changes - smtputf8
------------------------
[Incompat 20141001] The default settings have changed for
append_dot_mydomain (new: no, old: yes), master.cf chroot (new:
n, old: y), and smtputf8 (new: yes, old: no).
[Incompat 20140714] After upgrading Postfix, "postfix reload" (or
start/stop) is required. Several Postfix-internal protocols have
been extended to support SMTPUTF8. Failure to reload or restart
will result in mail staying queued, while Postfix daemons log
warning messages about unexpected attributes.
[Feature 20140715] Support for Email Address Internationalization
(EAI) as defined in RFC 6531..6533. This supports UTF-8 in SMTP/LMTP
sender addresses, recipient addresses, and message header values.
The implementation is based on initial work by Arnt Gulbrandsen
that was funded by CNNIC.
See SMTPUTF8_README for a description of Postfix SMTPUTF8 support.
[Feature 20150112] UTF-8 Casefolding support for Postfix lookup
tables and matchlists (mydestination, relay_domains, etc.). This
is enabled only with "smtpuf8 = yes".
[Feature 20150112] With smtputf8_enable=yes, SMTP commands with
UTF-8 syntax errors are rejected, table lookup results with invalid
UTF-8 syntax are handled as configuration errors, and UTF-8 syntax
errors in policy server replies result in execution of the policy
server's default action.
Major changes - tls support
---------------------------
(see "Major changes - delivery status notifications" above for
turning 4XX soft errors into 5XX bounces when a remote SMTP server
does not offer STARTTLS support).
[Feature 20140209] the Postfix SMTP client now also falls back to
plaintext when TLS fails AFTER the TLS protocol handshake.
[Feature 20140218] The Postfix SMTP client now requires that a queue
file is older than $minimal_backoff_time, before falling back from
failed TLS to plaintext (both during or after the TLS handshake).
[Feature 20141021] Per IETF TLS WG consensus, the tls_session_ticket_cipher
default setting was changed from aes-128-cbc to aes-256-cbc.
[Feature 20150116] TLS wrappermode support in the Postfix smtp(8)
client (new smtp_tls_wrappermode parameter) and in posttls-finger(1)
(new -w option). There still is life in that deprecated protocol,
and people should not have to jump hoops with stunnel.

The system administrator can set up one or more system-wide send-
mail-style alias databases. Users can have sendmail-style ~/.forward
files. Mail for name is delivered to the alias name, to destinations
in ~name/.forward, to the mailbox owned by the user name, or it is sent

log
@This is the Postfix 3.5 (stable) release.
The stable Postfix release is called postfix-3.5.x where 3=major
release number, 5=minor release number, x=patchlevel. The stable
release never changes except for patches that address bugs or
emergencies. Patches change the patchlevel and the release date.
New features are developed in snapshot releases. These are called
postfix-3.6-yyyymmdd where yyyymmdd is the release date (yyyy=year,
mm=month, dd=day). Patches are never issued for snapshot releases;
instead, a new snapshot is released.
The mail_release_date configuration parameter (format: yyyymmdd)
specifies the release date of a stable release or snapshot release.
If you upgrade from Postfix 3.3 or earlier, read RELEASE_NOTES-3.4
before proceeding.
License change

This software is distributed with a dual license: in addition to the
historical IBM Public License 1.0, it is now also distributed with the
more recent Eclipse Public License 2.0. Recipients can choose to take
the software under the license of their choice. Those who are more
comfortable with the IPL can continue with that license.
Major changes - multiple relayhost in SMTP
------------------------------------------
[Feature 20200111] the Postfix SMTP and LMTP client support a list
of nexthop destinations separated by comma or whitespace. These
destinations will be tried in the specified order.
The list form can be specified in relayhost, transport_maps,
default_transport, and sender_dependent_default_transport_maps.
Examples:
/etc/postfix/main.cf:
relayhost = foo.example, bar.example
default_transport = smtp:foo.example, bar.example.
NOTE: this is an SMTP and LMTP client feature. It does not work for
other Postfix delivery agents.
Major changes - certificate access
----------------------------------
[Feature 20190517] Search order support for check_ccert_access.
Search order support for other tables is in design (canonical_maps,
virtual_alias_maps, transport_maps, etc.).
The following check_ccert_access setting uses the built-in search
order: it first looks up the client certificate fingerprint, then
the client certificate public-key fingerprint, and it stops when a
decision is made.
/etc/postfix/main.cf:
smtpd_mumble_restrictions =
...
check_ccert_access hash:/etc/postfix/ccert-access
...
The following setting, with explicit search order, produces the
exact same result:
/etc/postfix/main.cf:
smtpd_mumble_restrictions =
...
check_ccert_access {
hash:/etc/postfix/ccert-access {
search_order = cert_fingerprint, pubkey_fingerprint } }
...
Support is planned for other certificate features.
Major changes - dovecot usability
---------------------------------
[Feature 20190615] The SMTP+LMTP delivery agent can now prepend
Delivered-To, X-Original-To and Return-Path headers, just like the
pipe(8) and local(8) delivery agents.
This uses the "flags=DORX" command-line flags in master.cf. See the
smtp(8) manpage for details.
This obsoletes the "lmtp_assume_final = yes" setting, and replaces
it with "flags=...X...", for consistency with the pipe(8) delivery
agent.
Major changes - forced expiration
---------------------------------
[Feature 20200202] Support to force-expire email messages. This
introduces new postsuper(1) command-line options to request expiration,
and additional information in mailq(1) or postqueue(1) output.
The forced-to-expire status is stored in a queue file attribute.
An expired message is returned to the sender when the queue manager
attempts to deliver that message (note that Postfix will never
deliver messages in the hold queue).
The postsuper(1) -e and -f options both set the forced-to-expire
queue file attribute. The difference is that -f will also release
a message if it is in the hold queue. With -e, such a message would
not be returned to the sender until it is released with -f or -H.
In the mailq(1) or postqueue(1) -p output, a forced-to-expire message
is indicated with # after the queue file name. In postqueue(1) JSON
output, there is a new per-message field "forced_expire" (with value
true or false) that shows the forced-to-expire status.
Major changes - haproxy2 protocol
---------------------------------
[Feature 20200112] Support for the haproxy v2 protocol. The Postfix
implementation supports TCP over IPv4 and IPv6, as well as non-proxied
connections; the latter are typically used for heartbeat tests.
The haproxy v2 protocol introduces no additional Postfix configuration.
The Postfix smtpd(8) and postscreen(8) daemons accept both v1 and
v2 protocol versions.
Major changes - logging
-----------------------
[Incompat 20191109] Postfix daemon processes now log the from= and
to= addresses in external (quoted) form in non-debug logging (info,
warning, etc.). This means that when an address localpart contains
spaces or other special characters, the localpart will be quoted,
for example:
from=<"name with spaces"@@example.com>
Older Postfix versions would log the internal (unquoted) form:
from=
LOCAL(8) LOCAL(8)
NAME
local - Postfix local mail delivery
SYNOPSIS
local [generic Postfix daemon options]
DESCRIPTION
The local(8) daemon processes delivery requests from the
Postfix queue manager to deliver mail to local recipients.
Each delivery request specifies a queue file, a sender
address, a domain or host to deliver to, and one or more
recipients. This program expects to be run from the mas-
ter(8) process manager.
The local(8) daemon updates queue files and marks recipi-
ents as finished, or it informs the queue manager that
delivery should be tried again at a later time. Delivery
status reports are sent to the bounce(8), defer(8) or
trace(8) daemon as appropriate.
CASE FOLDING
All delivery decisions are made using the bare recipient
name (i.e. the address localpart), folded to lower case.
See also under ADDRESS EXTENSION below for a few excep-
tions.
SYSTEM-WIDE AND USER-LEVEL ALIASING
The system administrator can set up one or more system-
wide sendmail-style alias databases. Users can have send-
mail-style ~/.forward files. Mail for name is delivered
to the alias name, to destinations in ~name/.forward, to
the mailbox owned by the user name, or it is sent back as
undeliverable.
The system administrator can specify a comma/space sepa-
rated list of ~/.forward like files through the for-
ward_path configuration parameter. Upon delivery, the
local delivery agent tries each pathname in the list until
a file is found.
Delivery via ~/.forward files is done with the privileges
of the recipient. Thus, ~/.forward like files must be
readable by the recipient, and their parent directory
needs to have "execute" permission for the recipient.
The forward_path parameter is subject to interpolation of
$user (recipient username), $home (recipient home direc-
tory), $shell (recipient shell), $recipient (complete
recipient address), $extension (recipient address exten-
sion), $domain (recipient domain), $local (entire recipi-
ent address localpart) and $recipient_delimiter. The forms
${name?value} and ${name:value} expand conditionally to
value when $name is (is not) defined. Characters that may
have special meaning to the shell or file system are
replaced by underscores. The list of acceptable charac-
ters is specified with the forward_expansion_filter con-
figuration parameter.
An alias or ~/.forward file may list any combination of
external commands, destination file names, :include:
directives, or mail addresses. See aliases(5) for a pre-
cise description. Each line in a user's .forward file has
the same syntax as the right-hand part of an alias.
When an address is found in its own alias expansion,
delivery is made to the user instead. When a user is
listed in the user's own ~/.forward file, delivery is made
to the user's mailbox instead. An empty ~/.forward file
means do not forward mail.
In order to prevent the mail system from using up unrea-
sonable amounts of memory, input records read from
:include: or from ~/.forward files are broken up into
chunks of length line_length_limit.
While expanding aliases, ~/.forward files, and so on, the
program attempts to avoid duplicate deliveries. The dupli-
cate_filter_limit configuration parameter limits the num-
ber of remembered recipients.
MAIL FORWARDING
For the sake of reliability, forwarded mail is re-submit-
ted as a new message, so that each recipient has a sepa-
rate on-file delivery status record.
In order to stop mail forwarding loops early, the software
adds an optional Delivered-To: header with the final enve-
lope recipient address. If mail arrives for a recipient
that is already listed in a Delivered-To: header, the mes-
sage is bounced.
MAILBOX DELIVERY
The default per-user mailbox is a file in the UNIX mail
spool directory (/var/mail/user or /var/spool/mail/user);
the location can be specified with the mail_spool_direc-
tory configuration parameter. Specify a name ending in /
for qmail-compatible maildir delivery.
Alternatively, the per-user mailbox can be a file in the
user's home directory with a name specified via the
home_mailbox configuration parameter. Specify a relative
path name. Specify a name ending in / for qmail-compatible
maildir delivery.
Mailbox delivery can be delegated to an external command
specified with the mailbox_command_maps and mailbox_com-
mand configuration parameters. The command executes with
the privileges of the recipient user (exceptions: sec-
ondary groups are not enabled; in case of delivery as
root, the command executes with the privileges of
default_privs).
Mailbox delivery can be delegated to alternative message
transports specified in the master.cf file. The mail-
box_transport_maps and mailbox_transport configuration
parameters specify an optional message transport that is
to be used for all local recipients, regardless of whether
they are found in the UNIX passwd database. The fall-
back_transport_maps and fallback_transport parameters
specify an optional message transport for recipients that
are not found in the aliases(5) or UNIX passwd database.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final envelope
recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines
beginning with "From ", and appends an empty line. The
mailbox is locked for exclusive access while delivery is
in progress. In case of problems, an attempt is made to
truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, prepends an X-Original-To: header with
the recipient address as given to Postfix, and prepends a
Return-Path: header with the envelope sender address.
EXTERNAL COMMAND DELIVERY
The allow_mail_to_commands configuration parameter
restricts delivery to external commands. The default set-
ting (alias, forward) forbids command destinations in
:include: files.
Optionally, the process working directory is changed to
the path specified with command_execution_directory (Post-
fix 2.2 and later). Failure to change directory causes
mail to be deferred.
The command_execution_directory parameter value is subject
to interpolation of $user (recipient username), $home
(recipient home directory), $shell (recipient shell),
$recipient (complete recipient address), $extension
(recipient address extension), $domain (recipient domain),
$local (entire recipient address localpart) and $recipi-
ent_delimiter. The forms ${name?value} and ${name:value}
expand conditionally to value when $name is (is not)
defined. Characters that may have special meaning to the
shell or file system are replaced by underscores. The
list of acceptable characters is specified with the execu-
tion_directory_expansion_filter configuration parameter.
The command is executed directly where possible. Assis-
tance by the shell (/bin/sh on UNIX systems) is used only
when the command contains shell magic characters, or when
the command invokes a shell built-in command.
A limited amount of command output (standard output and
standard error) is captured for inclusion with non-deliv-
ery status reports. A command is forcibly terminated if
it does not complete within command_time_limit seconds.
Command exit status codes are expected to follow the con-
ventions defined in <sysexits.h>. Exit status 0 means
normal successful completion.
Postfix version 2.3 and later support RFC 3463-style
enhanced status codes. If a command terminates with a
non-zero exit status, and the command output begins with
an enhanced status code, this status code takes precedence
over the non-zero exit status.
A limited amount of message context is exported via envi-
ronment variables. Characters that may have special mean-
ing to the shell are replaced by underscores. The list of
acceptable characters is specified with the command_expan-
sion_filter configuration parameter.
SHELL The recipient user's login shell.
HOME The recipient user's home directory.
USER The bare recipient name.
EXTENSION
The optional recipient address extension.
DOMAIN The recipient address domain part.
LOGNAME
The bare recipient name.
LOCAL The entire recipient address localpart (text to the
left of the rightmost @@ character).
ORIGINAL_RECIPIENT
The entire recipient address, before any address
rewriting or aliasing (Postfix 2.5 and later).
RECIPIENT
The entire recipient address.
SENDER The entire sender address.
Additional remote client information is made available via
the following environment variables:
CLIENT_ADDRESS
Remote client network address. Available as of
Postfix 2.2.
CLIENT_HELO
Remote client EHLO command parameter. Available as
of Postfix 2.2.
CLIENT_HOSTNAME
Remote client hostname. Available as of Postfix
2.2.
CLIENT_PROTOCOL
Remote client protocol. Available as of Postfix
2.2.
SASL_METHOD
SASL authentication method specified in the remote
client AUTH command. Available as of Postfix 2.2.
SASL_SENDER
SASL sender address specified in the remote client
MAIL FROM command. Available as of Postfix 2.2.
SASL_USERNAME
SASL username specified in the remote client AUTH
command. Available as of Postfix 2.2.
The PATH environment variable is always reset to a system-
dependent default path, and environment variables whose
names are blessed by the export_environment configuration
parameter are exported unchanged.
The current working directory is the mail queue directory.
The local(8) daemon prepends a "From sender time_stamp"
envelope header to each message, prepends an X-Original-
To: header with the recipient address as given to Postfix,
prepends an optional Delivered-To: header with the final
recipient envelope address, prepends a Return-Path: header
with the sender envelope address, and appends no empty
line.
EXTERNAL FILE DELIVERY
The delivery format depends on the destination filename
syntax. The default is to use UNIX-style mailbox format.
Specify a name ending in / for qmail-compatible maildir
delivery.
The allow_mail_to_files configuration parameter restricts
delivery to external files. The default setting (alias,
forward) forbids file destinations in :include: files.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final recipient
envelope address, prepends a > character to lines begin-
ning with "From ", and appends an empty line. The enve-
lope sender address is available in the Return-Path:
header. When the destination is a regular file, it is
locked for exclusive access while delivery is in progress.
In case of problems, an attempt is made to truncate a reg-
ular file to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, and prepends an X-Original-To: header
with the recipient address as given to Postfix. The enve-
lope sender address is available in the Return-Path:
header.
ADDRESS EXTENSION
The optional recipient_delimiter configuration parameter
specifies how to separate address extensions from local
recipient names.
For example, with "recipient_delimiter = +", mail for
name+foo is delivered to the alias name+foo or to the
alias name, to the destinations listed in ~name/.for-
ward+foo or in ~name/.forward, to the mailbox owned by the
user name, or it is sent back as undeliverable.
DELIVERY RIGHTS
Deliveries to external files and external commands are
made with the rights of the receiving user on whose behalf
the delivery is made. In the absence of a user context,
the local(8) daemon uses the owner rights of the :include:
file or alias database. When those files are owned by the
superuser, delivery is made with the rights specified with
the default_privs configuration parameter.
STANDARDS
RFC 822 (ARPA Internet Text Messages)
RFC 3463 (Enhanced status codes)
DIAGNOSTICS
Problems and transactions are logged to syslogd(8). Cor-
rupted message files are marked so that the queue manager
can move them to the corrupt queue afterwards.
Depending on the setting of the notify_classes parameter,
the postmaster is notified of bounces and of other trou-
ble.
SECURITY
The local(8) delivery agent needs a dual personality 1) to
access the private Postfix queue and IPC mechanisms, 2) to
impersonate the recipient and deliver to recipient-speci-
fied files or commands. It is therefore security sensi-
tive.
The local(8) delivery agent disallows regular expression
substitution of $1 etc. in alias_maps, because that would
open a security hole.
The local(8) delivery agent will silently ignore requests
to use the proxymap(8) server within alias_maps. Instead
it will open the table directly. Before Postfix version
2.2, the local(8) delivery agent will terminate with a
fatal error.
BUGS
For security reasons, the message delivery status of
external commands or of external files is never check-
pointed to file. As a result, the program may occasionally
deliver more than once to a command or external file. Bet-
ter safe than sorry.
Mutually-recursive aliases or ~/.forward files are not
detected early. The resulting mail forwarding loop is
broken by the use of the Delivered-To: message header.
CONFIGURATION PARAMETERS
Changes to main.cf are picked up automatically, as
local(8) processes run for only a limited amount of time.

NAME
local - Postfix local mail delivery
SYNOPSIS
local [generic Postfix daemon options]
DESCRIPTION
The local(8) daemon processes delivery requests from the
Postfix queue manager to deliver mail to local recipients.
Each delivery request specifies a queue file, a sender
address, a domain or host to deliver to, and one or more
recipients. This program expects to be run from the mas-
ter(8) process manager.
The local(8) daemon updates queue files and marks recipi-
ents as finished, or it informs the queue manager that
delivery should be tried again at a later time. Delivery
status reports are sent to the bounce(8), defer(8) or
trace(8) daemon as appropriate.
CASE FOLDING
All delivery decisions are made using the bare recipient
name (i.e. the address localpart), folded to lower case.
See also under ADDRESS EXTENSION below for a few excep-
tions.
SYSTEM-WIDE AND USER-LEVEL ALIASING
The system administrator can set up one or more system-
wide sendmail-style alias databases. Users can have send-
mail-style ~/.forward files. Mail for name is delivered
to the alias name, to destinations in ~name/.forward, to
the mailbox owned by the user name, or it is sent back as
undeliverable.
The system administrator can specify a comma/space sepa-
rated list of ~/.forward like files through the for-
ward_path configuration parameter. Upon delivery, the
local delivery agent tries each pathname in the list until
a file is found.
Delivery via ~/.forward files is done with the privileges
of the recipient. Thus, ~/.forward like files must be
readable by the recipient, and their parent directory
needs to have "execute" permission for the recipient.
The forward_path parameter is subject to interpolation of
$user (recipient username), $home (recipient home direc-
tory), $shell (recipient shell), $recipient (complete
recipient address), $extension (recipient address exten-
sion), $domain (recipient domain), $local (entire recipi-
ent address localpart) and $recipient_delimiter. The forms
${name?value} and ${name:value} expand conditionally to
value when $name is (is not) defined. Characters that may
have special meaning to the shell or file system are
replaced by underscores. The list of acceptable charac-
ters is specified with the forward_expansion_filter con-
figuration parameter.
An alias or ~/.forward file may list any combination of
external commands, destination file names, :include:
directives, or mail addresses. See aliases(5) for a pre-
cise description. Each line in a user's .forward file has
the same syntax as the right-hand part of an alias.
When an address is found in its own alias expansion,
delivery is made to the user instead. When a user is
listed in the user's own ~/.forward file, delivery is made
to the user's mailbox instead. An empty ~/.forward file
means do not forward mail.
In order to prevent the mail system from using up unrea-
sonable amounts of memory, input records read from
:include: or from ~/.forward files are broken up into
chunks of length line_length_limit.
While expanding aliases, ~/.forward files, and so on, the
program attempts to avoid duplicate deliveries. The dupli-
cate_filter_limit configuration parameter limits the num-
ber of remembered recipients.
MAIL FORWARDING
For the sake of reliability, forwarded mail is re-submit-
ted as a new message, so that each recipient has a sepa-
rate on-file delivery status record.
In order to stop mail forwarding loops early, the software
adds an optional Delivered-To: header with the final enve-
lope recipient address. If mail arrives for a recipient
that is already listed in a Delivered-To: header, the mes-
sage is bounced.
MAILBOX DELIVERY
The default per-user mailbox is a file in the UNIX mail
spool directory (/var/mail/user or /var/spool/mail/user);
the location can be specified with the mail_spool_direc-
tory configuration parameter. Specify a name ending in /
for qmail-compatible maildir delivery.
Alternatively, the per-user mailbox can be a file in the
user's home directory with a name specified via the
home_mailbox configuration parameter. Specify a relative
path name. Specify a name ending in / for qmail-compatible
maildir delivery.
Mailbox delivery can be delegated to an external command
specified with the mailbox_command_maps and mailbox_com-
mand configuration parameters. The command executes with
the privileges of the recipient user (exceptions: sec-
ondary groups are not enabled; in case of delivery as
root, the command executes with the privileges of
default_privs).
Mailbox delivery can be delegated to alternative message
transports specified in the master.cf file. The mail-
box_transport_maps and mailbox_transport configuration
parameters specify an optional message transport that is
to be used for all local recipients, regardless of whether
they are found in the UNIX passwd database. The fall-
back_transport_maps and fallback_transport parameters
specify an optional message transport for recipients that
are not found in the aliases(5) or UNIX passwd database.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final envelope
recipient address, prepends a Return-Path: header with the
envelope sender address, prepends a > character to lines
beginning with "From ", and appends an empty line. The
mailbox is locked for exclusive access while delivery is
in progress. In case of problems, an attempt is made to
truncate the mailbox to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, prepends an X-Original-To: header with
the recipient address as given to Postfix, and prepends a
Return-Path: header with the envelope sender address.
EXTERNAL COMMAND DELIVERY
The allow_mail_to_commands configuration parameter
restricts delivery to external commands. The default set-
ting (alias, forward) forbids command destinations in
:include: files.
Optionally, the process working directory is changed to
the path specified with command_execution_directory (Post-
fix 2.2 and later). Failure to change directory causes
mail to be deferred.
The command_execution_directory parameter value is subject
to interpolation of $user (recipient username), $home
(recipient home directory), $shell (recipient shell),
$recipient (complete recipient address), $extension
(recipient address extension), $domain (recipient domain),
$local (entire recipient address localpart) and $recipi-
ent_delimiter. The forms ${name?value} and ${name:value}
expand conditionally to value when $name is (is not)
defined. Characters that may have special meaning to the
shell or file system are replaced by underscores. The
list of acceptable characters is specified with the execu-
tion_directory_expansion_filter configuration parameter.
The command is executed directly where possible. Assis-
tance by the shell (/bin/sh on UNIX systems) is used only
when the command contains shell magic characters, or when
the command invokes a shell built-in command.
A limited amount of command output (standard output and
standard error) is captured for inclusion with non-deliv-
ery status reports. A command is forcibly terminated if
it does not complete within command_time_limit seconds.
Command exit status codes are expected to follow the con-
ventions defined in <sysexits.h>. Exit status 0 means
normal successful completion.
Postfix version 2.3 and later support RFC 3463-style
enhanced status codes. If a command terminates with a
non-zero exit status, and the command output begins with
an enhanced status code, this status code takes precedence
over the non-zero exit status.
A limited amount of message context is exported via envi-
ronment variables. Characters that may have special mean-
ing to the shell are replaced by underscores. The list of
acceptable characters is specified with the command_expan-
sion_filter configuration parameter.
SHELL The recipient user's login shell.
HOME The recipient user's home directory.
USER The bare recipient name.
EXTENSION
The optional recipient address extension.
DOMAIN The recipient address domain part.
LOGNAME
The bare recipient name.
LOCAL The entire recipient address localpart (text to the
left of the rightmost @@ character).
ORIGINAL_RECIPIENT
The entire recipient address, before any address
rewriting or aliasing (Postfix 2.5 and later).
RECIPIENT
The entire recipient address.
SENDER The entire sender address.
Additional remote client information is made available via
the following environment variables:
CLIENT_ADDRESS
Remote client network address. Available as of
Postfix 2.2.
CLIENT_HELO
Remote client EHLO command parameter. Available as
of Postfix 2.2.
CLIENT_HOSTNAME
Remote client hostname. Available as of Postfix
2.2.
CLIENT_PROTOCOL
Remote client protocol. Available as of Postfix
2.2.
SASL_METHOD
SASL authentication method specified in the remote
client AUTH command. Available as of Postfix 2.2.
SASL_SENDER
SASL sender address specified in the remote client
MAIL FROM command. Available as of Postfix 2.2.
SASL_USERNAME
SASL username specified in the remote client AUTH
command. Available as of Postfix 2.2.
The PATH environment variable is always reset to a system-
dependent default path, and environment variables whose
names are blessed by the export_environment configuration
parameter are exported unchanged.
The current working directory is the mail queue directory.
The local(8) daemon prepends a "From sender time_stamp"
envelope header to each message, prepends an X-Original-
To: header with the recipient address as given to Postfix,
prepends an optional Delivered-To: header with the final
recipient envelope address, prepends a Return-Path: header
with the sender envelope address, and appends no empty
line.
EXTERNAL FILE DELIVERY
The delivery format depends on the destination filename
syntax. The default is to use UNIX-style mailbox format.
Specify a name ending in / for qmail-compatible maildir
delivery.
The allow_mail_to_files configuration parameter restricts
delivery to external files. The default setting (alias,
forward) forbids file destinations in :include: files.
In the case of UNIX-style mailbox delivery, the local(8)
daemon prepends a "From sender time_stamp" envelope header
to each message, prepends an X-Original-To: header with
the recipient address as given to Postfix, prepends an
optional Delivered-To: header with the final recipient
envelope address, prepends a > character to lines begin-
ning with "From ", and appends an empty line. The enve-
lope sender address is available in the Return-Path:
header. When the destination is a regular file, it is
locked for exclusive access while delivery is in progress.
In case of problems, an attempt is made to truncate a reg-
ular file to its original length.
In the case of maildir delivery, the local daemon prepends
an optional Delivered-To: header with the final envelope
recipient address, and prepends an X-Original-To: header
with the recipient address as given to Postfix. The enve-
lope sender address is available in the Return-Path:
header.
ADDRESS EXTENSION
The optional recipient_delimiter configuration parameter
specifies how to separate address extensions from local
recipient names.
For example, with "recipient_delimiter = +", mail for
name+foo is delivered to the alias name+foo or to the
alias name, to the destinations listed in ~name/.for-
ward+foo or in ~name/.forward, to the mailbox owned by the
user name, or it is sent back as undeliverable.
DELIVERY RIGHTS
Deliveries to external files and external commands are
made with the rights of the receiving user on whose behalf
the delivery is made. In the absence of a user context,
the local(8) daemon uses the owner rights of the :include:
file or alias database. When those files are owned by the
superuser, delivery is made with the rights specified with
the default_privs configuration parameter.
STANDARDS
RFC 822 (ARPA Internet Text Messages)
RFC 3463 (Enhanced status codes)
DIAGNOSTICS
Problems and transactions are logged to syslogd(8). Cor-
rupted message files are marked so that the queue manager
can move them to the corrupt queue afterwards.
Depending on the setting of the notify_classes parameter,
the postmaster is notified of bounces and of other trou-
ble.
SECURITY
The local(8) delivery agent needs a dual personality 1) to
access the private Postfix queue and IPC mechanisms, 2) to
impersonate the recipient and deliver to recipient-speci-
fied files or commands. It is therefore security sensi-
tive.
The local(8) delivery agent disallows regular expression
substitution of $1 etc. in alias_maps, because that would
open a security hole.
The local(8) delivery agent will silently ignore requests
to use the proxymap(8) server within alias_maps. Instead
it will open the table directly. Before Postfix version
2.2, the local(8) delivery agent will terminate with a
fatal error.
BUGS
For security reasons, the message delivery status of
external commands or of external files is never check-
pointed to file. As a result, the program may occasionally
deliver more than once to a command or external file. Bet-
ter safe than sorry.
Mutually-recursive aliases or ~/.forward files are not
detected early. The resulting mail forwarding loop is
broken by the use of the Delivered-To: message header.
CONFIGURATION PARAMETERS
Changes to main.cf are picked up automatically, as
local(8) processes run for only a limited amount of time.
