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.
