This plugin enables the scanning of incoming mail received from a POP, IMAP, or LOCAL account using SpamAssassin. It can optionally delete mail identified as spam or save it to a designated folder, and also can be used to train a local SpamAssassin (or a remote one if SpamAssassin >= 3.1 is installed both locally and remotely). According to your SpamAssassin server configuration, it can show worse performance than Bogofilter, (slower, eating more CPU), but can catch spam with better accuracy.
