hi. i use ASSP and Postgrey. ASSP is a perl based smtp proxy, anti-spam. First time i used it, spam was reduced by about 95%. But spam emails change from time to time, the contents of the mail itself i mean. Most spam today have gif attachments so anti-spam solutions using regex won't be able to help much. that's where Postgrey comes in. It checks header properties such as source ip and email address, not the body, and rejects all mails temporarily (sends a 450 smtp message: greylisting in a nutshell). check it out.
http://assp.sourceforge.net and google for postgrey. God bless. hth.

Is there a way to make it more effective?
