www.untangle.com The basic setup is free. It does spam filtering, content filtering, malware protection... If you opt for the monthly subscription there are add-ons like AD integration and so on... It runs on a fairly small PC - depending on the amount of users.

We did have mailwasher but due to the opensource version being crap and the enterprise version costing as much as putting an entire detriot high school through college, I'm looking for another free/open-source spam product that actually works. Ideas?
