Victory over spam?

John Udell says that SpamBayes does a good enough filtering job to allow him to declare victory over spam. I’m skeptical, though I’ve had relatively good results with PopFile’s Bayesian filter and I’m sure its algorithms can be improved upon. I plan to try SpamBayes as soon as I can; for now, it’s only available as an Outlook plugin or by using the CVS binaries, which I don’t want to deal with.
