Steven uses advanced artificial intelligence to stop spam, using no key lists, key words, or fancy algorithms--just simple common sense. All features are enabled in the trial version, and there is no obligation to upgrade to a paid version. Steven supports POP accounts, Hotmail, Microsoft Exchange, and a complete host of other mail configurations. View the online tour at the Steven home page and see for yourself the list of features that make dealing with spam a breeze. Also, introduce artificial intelligence to your e-mail control. Steven uses the new Microsoft .NET framework for next-generation software. Members of the media, charities, and nonprofit organizations can apply for free registration. Features include mail-server functionality, an attachment-filing system, whitelist and blacklist drill-downs, and an all-new help file. Version 4.2 features unspecified improvements and bug fixes.

In the trial version, a message appears after every 50 spams.
