libmail-dkim-perl 1.20230212-1 (amd64 binary) in ubuntu lunar

 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.
