SpamAssassin Addons

Updaitng spamassassin with new blacklists is pretty easy.

Been running SpamAssassin on the mail server for quite some time.
The following .cf files have reduced the amount of spam by a noticeable bit.

http://www.stearns.org/sa-blacklist/sa-blacklist.current
http://mywebpages.comcast.net/mkettler/sa/antidrug.cf
http://www.merchantsoverseas.com/wwwroot/gorilla/bigevil.cf

Throw them in your /etc/mail/spamassassin/ directory and restart spamd. Oh yeah, make sure and : mv sa-blacklist.current 50blacklist.cf.
Make sure you keep them up to date, that way you will be blocking all the new stuff..
