Freeware Spam Filter

[glennda]

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!

has spamassassin built in

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.

Can this work alongside Exchange 2003 somehow? Quite liked GFI Mail Essentials effectiveness, but couldn't get the budget for it.

I'm confused as to what your asking? Is the above not what your after? Or are you expecting your users to spam each other?
