Freeware Spam Filter

**glennda** · 17th May 2010, 04:25 PM

I am looking into putting in an extra spam filter as our lea's seems to be getting a little lax. I was planning on just changing the forward on our firewall to direct the incoming SMTP traffic to a spam filter (preferably a linux one as would be free) which would then forward onto our exchange box.

Does anybody have any suggestions of a good free spam filter that they use?

I had a quick google and ASSP (anti-spam SMTP proxy) came up which looks like it would do the job.

any suggestions welcome

Thanks in advance

I use SpamAssassin: Welcome to SpamAssassin on my webserver at the moment and it does a pretty good job.

If you have exchange 2003 onwards you already have anti-spam built in, probably just needs tuning.

I would rather put something in the way to be perfectly honest! our exchange box was never setup very well and can be a little flakey (predecessor who didn't quite know what he was doing) and im just waiting for the day i can upgrade it to exchange 2010 and get rid of that box! but that's a summer job!

Can you tell Spam Filter is better or Anti-Virus software is better?

Our SMTP is scanned for viruses on its way in and when we send it to our LEA's smart host. We just want to put a Spam filter to try and reduce the spam coming through

Another vote for MailScanner. I have a box set up with postfix, mailscanner, spamassassin, and clamav. Ever since installing this we have been catching 99% of spam. Highly recommended.
