Message handling system for automated gateway between first and second handling systems wherein first envelope is added to a second envelope respectively without changing text

摘要

An automated gateway system for interfacing a first message handling system with a second message handling system. In the preferred embodiment, the automated gateway of the present invention allows the exchange between a formal system such as the United States Department of Defense AUTODIN message handling system and an informal system such as the International Standards Organization X.400 message handling system. Messages received from a first one of the message handling systems are processed and sent to a message routing unit which determines if the message should be sent to the first or second message handling system. If the second message handling system address exists, an automated gateway user agent validates the address and creates a second message handling system envelope around the entire message and submits it to the second message handling system.
