||MessageAuthority is a Spam filter that integrates into Outlook and Outlook Express to prevent junk mail from reaching your inbox. The core engine starts with a base analysis of over 35,000 spam messages. It adds a toolbar to Outlook and Outlook Express and automatically configures itself the first time you start Outlook. Its self tuning engine learns from the e-mail that you receive and if a spam happens to make it to your inbox, simply push the Spam button on the toolbar and MessageAuthority fine tunes the filter for you. MessageAuthority also includes other standard Spam detection techniques such as Friends Lists, Block Lists, and Challenge\Response, giving you more control over how your e-mail is handled.
