The SpamBayes classification sorts out virtually all spam messages and almost never produces a false positive -- that is, a good message wrongly identified as spam. Only once have I had to fetch an email from the junk mail folder. This happened when a Spanish friend wrote me, presumably because Spanish messages are rare in my inbox. I corrected the wrong classification, and all her subsequent messages were recognized as good. The program improves precision with each manual correction. SpamBayes can be run as an Outlook plugin under Windows or as a POP3 or IMAP proxy under Windows, Linux/Unix, and Mac OS.
