Personally I believe in a multi-tiered approach instead of depending on 
one item.

Right now, I have clamav at http://www.clamav.net scanning all e-mails 
coming in. I am using the trashscan filter from the system procmailrc 
which is located in the clamav contrib directory.

Then I have John's script next.

You cannot be to safe...
