I looked to procmail to filter spam too, but I found a solution which
takes care of all of that by using MailScanner
(http://www.mailscanner.info) This program uses other tools to scan
for viruses and spam (dangerous content), is quick and has low
overhead. It integrates all these programs that you never know you
have so many tools working together. So with MailScanner, I am also
a) SpamAssassin 2.63 (www.spamassassin.org) - using the RPM's available there
b) Active Spam Killer 2.4.1 (www.paganini.net/ask/) - a
c) ClamAV 0.65 (www.clamav.net) for virus scanning
d) MailWatch (mailwatch.sourceforge.net) - web frontend for
MailScanner (very cool!)
I had been running just Sendmail, and was using RBL to filter our
spam. I was getting more and more false positives this way, and
somehow more and more spam was getting through.
I installed ASK (Active Spam Killer) and instantly, spam was no
longer an issue. Users can monitor and configure thier Queue and
White/Black/Ignore lists via email. This was a godsend and installed
in like 15 minutes!
Then MyDoom hit, some of our machines became virus infected. I had
seen MailScanner before, and wrongly thinking that this was a Virus
Scanner at the MTA level. I downloaded it and then learned that it
was so much more. Excited about it, I had it installed and running in
about an hour (including SpamAssassin!) I then downloaded and
installed ClamAV, set it up to auto update every few hours.
I then learned of MailWatch (I don't remember where) and downloaded
and installed this. This is great because now I can monitor incoming
mail and see that MailScanner is actually working. With it, you can
teach SpamAssassin what is or is not Spam and this has really helped.
MailWatch is really worth having.
The whole system was a breeze to set up. Maintaining it is even
easier. I don't know how we got by without it. Needless to say, I
have ditched the RBL system altogether.
