When I was running an Exchange consulting gig at a big oil company (100,000+ seats) we used Tumbleweed's product. The thing I really liked about their product was that it is very fast and VERY flexible (SQL backend\web front-end). We were using it for keyword filtering (string matching (with wildcards) with a point scale, so each string has a point value...once the defined threshold for that value it reached while reading through a message it does the desired action on a message) and for AV scanning. You can use a number of different scan engines (I seem to remember using Norton's, but the point is you can choose so you can have a different engine on the SMTP scanner then you do downstream). This was by far the best SMTP scanner I have worked with to date.
Anyhow...I highly recommend it as it is fast, flexible, and the support was excellent (plus I believe it does everything that you require). -Steve > I'm looking for a new AV gateway product.
