I am using a freeware spam filter called K9 from www.keir.net. It works GREAT after I got it trained. However, I was wondering if there is another similar freeware program out there that is more tightly integrated into Outlook. I would like to have buttons in outlook that I can hit to mark messages as Spam and delete them outmatically when the rare spam message passes through. Anything like that available that is based on the Bayesian filtering process??
