I use rblsmtpd, and a local RBL style domain, which allows me
to block off whole netblocks with a 'dig' command and a couple
of Python scripts. Also allows me to give a customized "middle
finger" bounce message to each domain. New spammers can be
blocked off within seconds of popping up.
Contact me off-list if you'd like more info.
