Hi - I just released BDKIM: a bridge from Java to Mail::DKIM so you can verify (not sign, yet) messages in Java using Mail::DKIM and get detailed results back (per signature). It includes a Perl-side server that listens on a port and a Java-side client (and API interface) that sends messages over and receives the results. In case it's useful to anyone: http://lacinato.com/cm/software/emailrelated/bdkim -Casey
