Have you looked at spamassassin? It's the main open source spam package in use.

See http://spamassassin.apache.org/

Whatever distro you use, ther is probably a spamassassin package available for it

SA lets you do a lot of things from baysian filtering to using RBL's and basic rule based filtering

Well, our current email provider uses spamassassin and and we still get at least 100 spam emails a day per user... That is why we want to bring it in house...

That probably would have been good info to include in you initial post too.

It depends how you set it up. As I said, there are a wide range of ways to configure SA. If your provider doesn't use bayes for example, this can improve things considerably.

Another mechanism that can help is greylisting. I don't know about sendmail, but postfix can use it. Greylisting is where your server maintains a list of other mail servers that have connected to yours, and new servers are given a server busy notification thereby requiring them to reconnect latter. Most spambots won't bother. Just a thought

I use qmail w/ clamav and spamassasin in combination with RBL ( Real Blacklisting) and it works pretty well. Its not 100% but I havent had any customers complain too much.

Ive never used it, but alot of people seem to really enjoy and have success with dspam.
