METHOD AND SYSTEM FOR RECOGNIZING DESIRED EMAIL

A system and method for recognizing an incoming email as a desired email examines outgoing email messages to arrange the email into fragments for which representations are created and stored. When an incoming message is received, the message is arranged into fragments for which representations are created. The representations of the incoming message are compared to the stored representations and if the matches between stored representations and the representations of the incoming message meet a predefined threshold test, the incoming message is recognized as being desirable. An incoming email message which has been recognized as being desirable can be subjected to a lesser examination to recognize a SPAM message, or to no further examination to recognize a SPAM message.
