Hello all does anyone know of a good spam filter/blocker for a mail gateway using Sendmail, and since its a mail gateway the users do not have accounts on the machine. I want to block spam before it gets into our network, and since the ussers don't actually have an account on our mail gateway, I have not been able to find software that will block mail for a setup like that.

Use MAPS lists, like RBL and DUL.

Scroll down to see the Sendmail Version 8.9 Use section.

I could be wrong but this looks like something to use to block people using your server as a spam relay, not something to limit the amount of email messages someone sends you that is spam

I use qmail, so I don't have first-hand experience with this, but it looks like this project might help you use spamassassin.

EDIT: added spamassassin.org link.

I second spamassassin. I had it installed on my mail machine for a while (well, it's a SLOW machine and has very little ram... alot of spam makes it take alot of ram and processor) and I had good results with it's filtering. I'd say I've only had 2 maybe 3 spam leak through when I was using it.

I had a couple of false alarms, so I changed the settings a bit and added a few phrases of my own into the config files. It's a nice app. If you have more than 64 megs of ram on your machine, it's nice. Otherwise, it's probably best not to try :P

I used a .forward file for this... you might do otherwise.
