New port: mail/spamd - Trapit in cooperation with security/pf
A Trapit is a fake SMTP server that tries to waste as much resources
of a spam-relay as possible - without delivering any mail.
Implemented for pf, but might work with other ip filters as well.
mail/relaydb is a fine tool to utilize spamd.
