To the contrary, I've been deploying on quite a few servers.  I wrote an 
updated version as an article for Free Software Magazine; it's available 
online at 
http://www.freesoftwaremagazine.com/free_issues/issue_02/focus_spam_postfix/ .

An associate and I are considering building little FreeBSD anti-spam 
appliances to sell to local businesses.

Just curious - do you still find this to be an effective solution, or
have you had to adapt or abandon it?

Killing spam on FreeBSD

2004-07-13 Thread Kirk Strauser
I recently started rejecting about 99.9% of incoming spam *without* using 
challenge-response or other load-increasing methods.  For details, read:

http://subwiki.honeypot.net/cgi-bin/view/Freebsd/FilterMailWithPostFix

In a nutshell, before implementing this plan, I was receiving about 600 
emails and 50 spams per day.  Afterward, I'm receiving about 600 emails and 
1 spam (yes, one) per day.  In other words, I don't seem to be having any 
false positives at all.
