I just got a note from Martijn Jongen mentioning that he has a SURBL filter for Exchange.

While I haven't examined it in detail, it certainly seems easier to install and configure than the regexfilter. When I get a few minutes, I'll poke into it and give it a try. However, Martijn's site has a pretty active user forum where many people have made happy noises about previous releases, so that's probably a good place to start reading.
