rangeva writes "As anti-spam solutions evolve to limit junk email, the senders quickly adapt to make sure their messages are seen. an interesting article describes the application of an artificial immune system model to effectively protect email users from unwanted messages. In particular, it tests a spam immune system against the publicly available SpamAssassin corpus of spam and non-spam. It does so by classifying email messages with the detectors produced by the immune system. The resulting system classifies the messages with accuracy similar to that of other spam filters, but it does so with fewer detectors."
