You may have been wondering why I've been going through the documentation for libOpenDKIM with a fine toothed comb. It is because I've been re-implementing part of the Mail::DKIM CPAN Module to use OpenDKIM instead. The work is now complete, so it is now possible to use OpenDKIM from a Perl program. The code has been released as open source; it is available via

I have been more thorough with the testing on the signing side than on the verification side, since that's the initial need here. I've written another CPAN module (Mail::OpenDKIM::Signer), which is like Mail::DKIM but uses OpenDKIM to do the legwork.

Initial findings show a 4-fold increase by using Mail::OpenDKIM over Mail::DKIM.

The code requires OpenDKIM 2.3.x.
