Summary of ANTI-spam techniques now available

I just finished a writeup which covers anti-spam methods using: - route filters - the sendmail check_* techniques - Eudora filters It includes complete example files (available inline or via FTP). I know when I started to implement the sendmail check_* rules I scratched my head a bit. And there are plenty of people who've never even seen a Cisco access-list. It's available now at: http://www.sprocket.com/Security/Stopping-UCE.html The more people running sites who have this information, the better.
