The present invention is a system and method for the identification and management of mass unsolicited e-mail, commonly known by the term "SPAM." The system and method function by assembling a group of users, identifying portions of all of the e-mail sent to those users, and then counting, among all of the users, the number of instances of receipt of identical pieces of e-mail.
