@Add libdkim: Portable library that signs and verifies emails

libdkim is a portable library that signs and verifies emails using the
OpenSSL library.

DomainKeys Identified Mail (DKIM) defines a domain-level authentication
framework for email using public-key cryptography and key server
technology to permit verification of the source and contents of messages
by either Mail Transport Agents (MTAs) or Mail User Agents (MUAs).

Fix build with newer OpenSSL (from FreeBSD).
