DMA has the best KIS, however, as you note it lacks key feature/s.  IMO,
it should be moved to ports.  Mailwrapper should be moved as well
(following the example of javavmwrapper).  We've had so many issues with
mailwrapper that it now is deleted on install, as well as **/etc/mail.

Until Postfix has a BSD-compatible license my vote goes to OpenSMTPD
configured not to listen to port 25 (for KIS and to keep it from being
shared with jail localhosts).
