Spam Reader is a MS Outlook plug-in that extends Outlook functionality with a Bayesian spam filter. There is no need to run an external program. Spam Reader fully integrates into MS Outlook. Spam Reader analyzes each message when you receive it and puts it in the Spam folder if needed. SpamReader does not break existing Outlook filtering rules. The Bayesian spam filter is self-trainable. You can also tune it up for better accuracy.
