Of course, I'm crazy enough to play with sendmail.cf. *grin* Rumour has it that Eric Allman is planning to include some anti-spam hacks in the next distribution; for those who are impatient, most of 'em are already available at various sites linked from http://spam.abuse.net/. If you're big on filtering, a combination of your idea, the various check_* hacks, TCP wrappers or other firewalling, and user-level Procmail should cut out a lot of spam; the reason I suggest a combination is because no one filtering method gets everything, and your script is perfect as a last-ditch effort for anything that somehow got through. (Quick off-topic plug: the best way to stop spam is to stop it at the source. http://www.cauce.org/ for more info. I'd rather not get into a discussion of that here, though, 'cause I'm already on lots of spam-related mailing lists.) ---------========== J.D.
