The invention is a system and method for eliminating unsolicited e-mail. The invention employs the simple approach of limiting correspondence to known correspondents through a system of authentication, while allowing persons who are not authenticated correspondents to petition correspondence by means of an extremely restrictive message format that is useless for marketing purposes. The system uses a Header Parser [102] to sort all incoming electronic mail into solicited and unsolicited messages without parsing the message body. It allows unauthenticated correspondents to solicit correspondence by means of a specially tagged message format called a Request Correspondence Message, and makes use of a Format Inspector [103] to ensure that all such solicitations meet strict format requirements which make it impraticable to use such messages for the purposes of marketing or solicitation. Authenticated Correspondents are managed for each user with an Authentication Key Database [106]. The integrity of the system is maintained by means of a transactional exchange of authentication keys, which are transformed with each exchange to prevent keys from being intercepted and reused. This method allows users to maintain absolutely unique key signatures, which can be attached to message headers and sent in, clear without fear of interception or spoofing. This safeguard makes it impossible to share, sell, or compromise users' correspondent lists, and makes this approach to eliminating unsolicited e-mail unique from any similar method that employs correspondent lists.
