SpamAI saves you time with improved accuracy by centralizing anti-spam efforts among multiple users and/or computers. One administrator manages several anti-spam mailboxes. Site specific rules under control of an administrator such as accept email from specific organizations can apply uniformly and instantly across multiple users with no effort on the part of final users. SpamAI filters 95-99% of spam using over 600 pattern matching rules on the entire message received, including headers and body. It is rarely fooled by misspellings such as "vi@gra". Indeed, SpamAI is programmed to look for spammer tricks such as sending invisible images to track you and SpamAI will mark email as SpamAI when such subterfuge is detected. When there is a new spammer trick deployed, SpamAI will shortly thereafter update its rule base automatically over the web. SpamAI has flexible configuration options which allow you to delete spam on your server without even reading it on your email client. All e-mail is kept for a month in the SpamAI archive on the installed machine by default so that e-mail is never lost. SpamAI can be setup on a single computer with a single user (Home Edition) or a central computer for multiple users (Business Edition). The SpamAI server component runs under Windows 2000, XP, and 2003 Server.
