ABSTRACT:
A sewer provides a message from a sender to a recipient and an attachment including the sender's identity, the recipient's identity and address, and the time of transmission from the sewer to the recipient. The method includes receiving the message and attachment at a sewer displaced from the recipient's location from the recipient and operates upon the message and attachment to allow comparison between information contained in the attachment and/or the message to determine the authenticity of the message.
