(*) Spam Trapper is a multilevel spam filter for Microsoft Outlook version 2000 and later. It is a plug-in component with clear convenient interface. (*) The first level checks your address book and validates all letters from your clients. So letters from your friends and colleagues are never processed as spam. (*) Other levels check message language, subject, body, http links and other mail feature. The filter has Special Statistical levels that are based on unique algorithms. The last level is a Bayes Filter. Such program architecture allows catching spam before the Bayes Filter is trained enough and minimizes the filter training period. Any level can be switched off. (*) There are non-spam related functions too. For Example, you can use Outlook as an alarm clock. But if you exit it by mistake alarm will not work. SpamTrap allows prevent Outlook from exiting. Instead it hides Outlook and sets an Outlook icon into the systray. So Outlook is always at hand and no alarm messages will be lost. Additional option makes Outlook to play Mp3 files and other media files.(*) Spam Trapper does not work with Outlook Express.
