Actually I've just completed an installation of Razor, which is the open-source predecessor to Cloudmark's SpamNet. Like SpamNet, Razor uses consensus votes to determine what is and is not spam, and by using a simple procmail script I have the software marking spam as described by the original poster. It is server-based.
Now the tricky part is that the spam nomination agent (razor-report) and the revocation agent (razor-revoke) are both un*x-based, so the average user is not going to be able to use them. It might be possible to set up a reporting mailbox to which the users could forward the spam and have a script report them, but let's think about that for a moment. They're users. The first person here who set up SpamNet was using it to report birthday announcements from our HR department. If you let the users decide what is spam, you'll break the model that Razor and SpamNet use: responsible reporting. For that reason alone I would prefer to have a human filter what users think is spam before reporting it. (As a side note, they are now weighing nominations and cancellations so that as a user you get a "reputation." People who falsely report spam eventually will just get ignored.) Now me, I'd suggest that we as Exchange admins lobby Cloudmark to develop a server-side, NT-based version of SpamNet with the possibility for client-side nominations. I've already emailed them about this and they say that their plans are indefinite. But if they see a market for it I suspect they will go in that direction. If you are comfortable with un*ces, go to http://razor.sourceforge.net/ to check out the package. It's quite nice. I am also an advocate of SpamNet on the client side (http://www.cloudmark.com/).
