Message-handling systems and protocols
Ian Cunningham · Proceedings of the IEEE · 1983
Message-Handling Systems provide store-and-forward electronic mail services. In 1984, CCITT will approve a set of Recommendations defining standards to interconnect systems throughout the world. This paper describes international efforts to develop the standards which are necessary for a worldwide electronic mail system. The system architecture, protocol structure, implementation options, and message transfer and interpersonal messaging services are described.
