See also /usr/ports/security/maia and /usr/ports/mail/mimedefang. I've used the first one to great effect, though we (unfortunately, to my mind) replaced it with a Barracuda appliance which did basically the same thing, and cost a lot more. I tried implementing mimedefang, but staff complained bitterly about their html-formatted emails being trashed.
