We filter everything that goes through our smtp server, the theory being
that if it goes through our pop3 server it went through our smtp first.
We use MIMEDefang and McAfee's virus engine, but there are others.
Mailscanner was mentioned recently on the list and looks like it does 
the same type of thing.
