I was hoping someone would bring up Exim. I currently have most of our
services (WWW, MySQL, DNS, RADIUS etc etc running on FreeBSD servers. The
one big exception is our mail server and the plans are to move it to
FreeBSD sometime during the next several months. Based on the little bit
of preliminary research I have done Exim seems to keep coming back to be
the front running contender for our MTA.

If you have any good basic tutuorial sites for Exim and needed
counterparts for virus scanning and  spam filtering with it please post
them. Thank you for your time.
