1. A system for securing messages comprising one or more computing devices of a restricted access network including:
- a computing device configured to function as a forward mediator of the restricted access network to;
receive an original plaintext message comprising an original recipient address having an original recipient domain,process the original message to provide a processed message, wherein the processing includes transforming at least a portion of the original plaintext message and the recipient address and replacing the original recipient domain by appending a different domain of a reverse mediator to cause a server to route the processed message via the reverse mediator, andforward the at least one processed message to the server of a messaging system of a public network; and
a computing device configured to function as a reverse mediator of the restricted access network to;
receive a processed message from the server, andprocess the received processed message to provide an unprocessed plaintext message for forwarding to a recipient.

Abstract
A system and method for secure use of messaging systems. A mediator may receive an original message, process the original message to produce a processed message, and may forward the processed message to a server or a messaging system. A mediator may receive a processed message from a server or a messaging system, process the received processed message to produce an unprocessed message that may be substantially identical to the original message and may forward the unprocessed message to a destination.

21. A method of securing messages in a restricted access network, the method comprising:
-
at a forward mediator of the restricted access network; receiving an original plaintext message comprising an original recipient address having an original recipient domain destined to a recipient; processing the original message to provide a processed message, wherein the processing includes transforming at least a portion of the original plaintext message and the recipient address and replacing the original recipient domain by appending a different domain of a reverse mediator to cause a server to route the processed message via the reverse mediator; forwarding the processed message to the server of a messaging system; at a reverse mediator of the restricted access network; receiving the processed message from the server; processing the received processed message to provide an unprocessed plaintext message; and forwarding the unprocessed message to the recipient. - View Dependent Claims (22, 23, 24, 25, 26, 27)
