take a look at MailScanner (www.mailscanner.info). The greatest thing since home-brewed beer, IMHO.

I used to run MailScanner, but then I switched to Exim+SA+Sophie. As Exim has now integrated the exiscan patch, it's much easier to set up. In addition, I find it extremely flexible, and uses less resources than MailScanner. In addition, I do not believe MailScanner will reject messages at smtp-time (if the spam score is greater than a threshold, or whatever rules you decide), which can cause problems. If my smtp server accepts the email, it's guaranteed to be delivered, which is how mail servers should be operate. There's no guarantee that a bounce message will ever get to its destination, especially not if it is spoofed, it's just a waste of time.
