RFC 4871, 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).
.
Mail::DKIM is a Perl implementation created by Jason Long of Messiah
College. It performs signing as well as signature verification. It
also supports the older DomainKeys standard.
.
This library further includes support for adding and verifying
Authenticated Received Chain (ARC; RFC 8617) assertions.
