SpamAI is a spam filtering program to block unwanted email. SpamAI can filter mail in multiple accounts per individual and for multiple individuals. The user interface is web-browser based so that users and administrator can flexibly be set up on any combination of the same and separate machines. Sophisticated rules are applied to both the content and headers of the email to mark it as spam or not. The spam can now be easily separated and handled as a class, usually by deleting it after a cursory review in one step. These rules based on training from looking at past spam. SpamAI is unusual in that its Live technology upgrades filtering rules and program code residing on your computer in near real time. You receive updates to filter out the latest spammer subterfuges within typically a half hour of posting. SpamAI uses Regular Expression (Regex) rules and makes their definition accessible to the user. Regex rules can be very simple for straight forward tasks such as constructing a list of people whose mail you want to receive. They can also handle sophisticated tasks such as recognizing variant spellings meant to evade filtering. SpamAI Regex rules allows specific email patterns to be targeted specifically without affecting any other rules. The Regex engine is exposed so power users and administrators can write their own filtering rules. You can see the effect of rule edits immediately for test cases or on the last 30 days worth of email received. All email is kept in a rotating archive that keeps the last month''s email received so that received email is never lost. If you delete an email unread and later decide you should read it, the email can be retrieved from the archive and read in your email program. SpamAI runs under either desktop or server versions of Windows and is suitable for businesses and individuals alike. SpamAI is compatible with your existing email clients such as Outlook, Outlook Express, Eudora, Mac/Linux clients, and many others.
