Jason:

You could easily setup a Linux box (pick your favorite flavor) and use
sendmail coupled with something like MailScanner
(http://www.sng.ecs.soton.ac.uk/mailscanner).  There are a number of mail
gateway filtering projects out there if you search using Google
(www.google.com) or visit SourceForge (www.sf.net) for open-source projects.

You can setup sendmail to relay mail for your domain on to your current mail
server.  Alternatively you could use a commercial product such as Trend
Micro InterScan VirusWall which as I recall is actually sendmail integrated
with their antivirus utilities.

I hope this helps point you in the right direction.
