ABSTRACT:
A method for identifying unsolicited electronic mail messages in a computer network. The method includes receiving an electronic mail message and removing non-static data from the electronic mail message. A checksum is generated based on data remaining within the electronic mail message and compared with a database containing checksums for previously identified unsolicited messages. The method further includes identifying the electronic message as an unsolicited message if the generated checksum matches one of the database checksums.
