Simple Mail Transfer Protocol (SMTP) was architected, designed, and implemented for the Transmission Control Protocol/Interchange Protocol (TCP/IP) to exchange mail. It is a store and forward mail application. Systems Network Architecture Distribution Services (SNADS) and Document Interchange Architecture (DIA) were architected for the SNA protocol to exchange documents. This new method uses the SMTP architecture with SNA architecture for mail exchange. This is accomplished by extending the "socket" interface of TCP/IP protocols to non-TCP/IP protocols, the first being SNA. This method also extends SNA to the "sendmail" router functions which use sockets and have SMTP imbedded in its design.
