Official ARPA-Internet Protocols RFC 944 oriented protocol, this document describes its TCP specification. SFTP uses only one TCP connection; whereas TFTP implements a connection over UDP, and FTP uses two TCP connections (one using the TELNET protocol). Please discuss any plans for implementation or use of this protocol with the contact. OTHER REFERENCES: DEPENDENCIES: Transmission Control Protocol CONTACT: MKL@MIT-XX.ARPA Simple Mail Transfer Protocol ------------------------------- (SMTP) STATUS: Recommended SPECIFICATION: RFC 821 (in "Internet Mail Protocols") COMMENTS: The procedure for transmitting computer mail between hosts. This has been revised since the IPTW, it is in the "Internet Mail Protocols" volume of November 1982. RFC 788 (in IPTW) is obsolete. There have been many misunderstandings and errors in the early implementations. Some documentation of these problems can be found in the file [ISIF]<SMTP>MAIL.ERRORS. Some minor differences between RFC 821 and RFC 822 should be resolved. OTHER REFERENCES: RFC 822 - Mail Header Format Standards This has been revised since the IPTW, it is in the "Internet Mail Protocols" volume of November 1982. RFC 733 (in IPTW) is obsolete. Further revision of RFC 822 is needed to correct some minor errors in the details of the specification.

This protocol utilizes the User Datagram Protocol (UDP) which in turn calls on the Internet Protocol to deliver its datagrams.

It is also designed to accommodate a variety of target CPU types. It provides a powerful set of debugging services, while at the same time, it is structured so that a simple subset may be implemented in applications like boot loading where efficiency and space are at a premium.
