Hello, I'm in the market for a new antispam solution. I've got one deployed and it's not working, it's not even tagging let alone stopping. I was wondering from those who use linux-based email servers, Postfix prefered but sendmail/exim will work as well, what are you using for your antispam measures? I'd prefer something that's not very resource intensive and if it can do antivirus that would be a plus. Also, anyone using any apps for groupware support? Thanks. Dave.
On a linux system, I really doubt anything can touch spamassassin for
effectiveness. I doubt even commercial products are significantly better. In
fact, I've had an on-going debate with one of the guys who do email for the
entire University of Wisconsin. I do it just for the Math department. But we
argued about it for years without either of us being able to prove an
advantage. Of course, I'd say that means I win because spamassassin is free
and its just little old me doing it all by myself whereas there is like 5 or
6 people involved in running the campus email system and they paid big money
for their spam filtering system. Spamassassin is the perfect example of the
beauty of open source software. There are literally thousands of sys admins
around the world contributing to the spamassassin rule set. You can
configure your Spamassassin instance to download new rules daily.
Last time I built a mail system was a couple of years ago. At the time
configuring spamassassin for virus filtering was non-trivial. You had to
install a couple of extra packages called amavis and clamav. But I think
it may be easier now because I believe there is a direct clamav plugin for
spamassassin. But there is a bzillion tutorials out there on how to do it.

I used postini, saved me messing with spam assassin and all those memory eating processes such as perl etc. It's $10 per user per year and any user not in the database just gets mail passed through. www.postini.com Other solutions like spam assassin and klamav do work but certainly take server resources especially if you receive a lot of mail.
