 From the MIMEDefang website:

It will detect a SpamAssassin and ClamAV installation and invoke it 
site-wide, rejecting virii and extreme spam before it gets to the

and sending a quarantine notification to the recipient.

Reading around, it looks like Postfix supports milters and people have 
gotten MD working with it.
