Abstract

The present invention discloses a method and apparatus for a user, either an originator or a receiver of an e-mail message, to erase the e-mail message from all servers which routed the message when the e-mail message is erased from the user'"'"'s client computer storage. By creating originator, server, and receiver delete tables, a pathway for a delete transaction containing the addresses of servers which routed the e-mail message enables the user, either an originator or receiver of the e-mail message, to sequentially delete the message along the pathway upon deletion from the client computer. Additionally, by inserting a deletion date into the header of the message, the message may be deleted from the client computer and all servers upon occurrence of the deletion date.

Claims
