I am so sick of spam!  I currently use MailWasherPro which is the update of the old free MailWasher.  However, I have been following a lot of the spam fighters that are using Bayesian Filtering to kill their unwanted mail.

What I am wondering is if anyone has done anything like this with C# or any other .NET language?  I have googled it on a regular basis but have come up empty.  If anyone has looked into this please let me know and I would be interested in helping.  Otherwise, I am probably going to attempt to port it from one of the several non-dotnet languages that use it.
