IMGATE project (http://imgate.meiway.com/)
*BSD/Linux + Postfix + IMGATE config = almost zero administration and users don't know
its there except for the drop in spam. Most of the IMGATE project users use FreeBSD
but it really works on any OS that can run Postfix. The IMGATE mailing list is very
active so its quite easy to get help if you need it. :)
Also if you use a *BSD/Linux Postfix outbound server you can speed up your mail
delivery... offloading outbound to a "smart host" makes exchange a happy camper.
