Paul Graham’s article, A Plan for Spam is a great read for anyone interested in ridding their inbox of unwanted messages. It also sparked a flurry of tools using Bayesian Filtering statistically filter spam. I set up Bogofilter and after only about 10 hours, it’s been catching almost everything. What it misses, Spamassassin catches and then updates the “bogosity” of the message so it gets caught next time.
