Bouncing spams generated even more spam. I get a mail box full of bounced spam messages that have a forged from address 100% of the time this will never get to a spammer the only possible ones it will stop are false positives which should be pretty rare anyway and if coupled with manual filtering/ checking of the spam before deleting can be avoided. The best method I have found to avoid the false positives is to be able to run your spam filter during the incoming smtp connection. But this requires the anti spam program to act as a transparent smtp server. This method will reject incoming spam so any false positives will be avoided BUT spam can still be bounced if it came from an open relay, as the open relay will just do the bouncing instead of your system. I use amavis and it is not transparent so I can only run amavis after postfix has received the mail and queued it.
