BDKIM
Last Updated: Wednesday, 17 September 2014
BDKIM ("Bridge to DKIM" or "Boxbe DKIM") is two pieces of software. Together they form a networked bridge from Java to the Mail::DKIM Perl module, allowing you to easily verify the DomainKeys and DKIM signatures for a given message. You could also write your own client (in whatever language) to talk to the BDKIM perl server. This distribution also includes an example usage Java class.
