The application software processes incoming mails from mail server such as IMS to eradicate spam at the server side therefore freeing the client mail from any spam. The mail administrator sets each mail account to a STF (Spam Tolerance Factor) that determines the number of spam this account can accept before shutting the sender off. AN STF of 0 will automatically block all mail sender that is not in the BuddyList. The Buddy List is auto-created for each mail sent by the user. The SpamList is also autocreated. Automatic removal from SpamList is done upon sending email to recipient from SpamList.
