Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) networks. SMTP was first defined in RFC 821 (STD 15),"rfc821">RFC 821, Simple Mail Transfer Protocol, J.B. Postel, The Internet Society (August 1982) and last updated by RFC 5321 (2008)"rfc5321">RFC 5321, Simple Mail Transfer Protocol, J. Klensin, The Internet Society (October 2008) which includes the extended SMTP (ESMTP) additions, and is the protocol in widespread use today. SMTP is specified for outgoing mail transport and uses port 25.
While electronic mail servers and other mail transfer agents use SMTP to send and receive mail messages, user-level client mail applications typically only use SMTP for sending messages to a mail server for relaying. For receiving messages, client applications usually use either the Post Office Protocol (POP) or the Internet Message Access Protocol (IMAP) to access their mail box accounts on a mail server.
History
Various forms of one-to-one electronic messaging were used in the 1960s. People communicated with one another using systems developed for specific mainframe computers. As more computers were interconnected, especially in the US Governments ARPANET, standards were developed to allow users using different systems to be able to e-mail one another. SMTP grew out of these standards developed during the 1970s.
SMTP can trace its roots to two implementations described in 1971, the Mail Box Protocol, which has been disputed to actually have been implemented,, Tom Van Vleck: "It is not clear this protocol was ever implemented" but is discussed in RFC 196 and other RFCs, and the SNDMSG program, which, according to RFC 2235, Ray Tomlinson of BBN "invents" for TENEX computers the sending of mail across the ARPANET., Ray Tomlinson, BBNPicture of "" by Dan Murphy, a PDP-10 Fewer than 50 hosts were connected to the ARPANET at this time.RFC 2235
