I am running spamassasin on my mail server (postfix) and am also rejecting email based on ordb.dk (open relay blacklist) and have been pretty satisfied with the setup. Recently thought more and more spam are slipping in.
So I would like to hear what you guys do to filter spam?
Checkout www.crunzh.com for nice freeware programs. Including a program for monitoring your webserver.
