At the moment we're running FreeBSD 4.x with postfix, clamav, and 
spamassassin via amavisd-new; after processing the message is injected 
into another postfix queue where it's forwarded to an internal mail 
server.  Is there an easy way to plug mimedefang into that kind of 
setup?  Is there a nice howto on the subject?
