FWIW, Storm Lake just bought TrimMail, an appliance to handle our spam. http://www.trimmail.com/
The company is from the Quad cities.(Gotta support IA companies when we can.) The appliance needed only a DNS change - updating the MX record. Mail goes to it first. The box's default setting of "5" missed 10% of our spam. Set now at "4," it catches 99% of our spam and gets better by the day, learning what's spam. It has had only 1 false positive in two weeks of running, now whitelisted, an insurance company that is normally "an online advertiser." (One of our users has a business acquaintance at the company.) It uses mostly bayesian filtering, running 10 tests. As each piece of mail gets one of the tests, it gets a score of zero or 1. As it gets to a total of 4 or greater, it gets labeled <<JUNK>> and can be auto-deleted by the appliance or the mail client. One of the tests is a service, updated weekly by the company. We've got it set to NOT autodelete so we can monitor false positives. With our users setting their mail clients to delete <<JUNK>> silently, it's been very nice. Now our "church lady" no longer gets "those" emails - you know the ones I mean. (Can't type it here or this'll get blocked.) I have regained 90 minutes/day not having to update blacklists. Life is good again.
