Email

Email is the most common used name for electronic mail that is used world-wide, wherever it has internet connections, and is a method of exchanging digital messages. This system is based on a model where email "server computer systems accept, forward, deliver and store messages" called a store-and-forward model. Email was originally transmitted directly from one person's device to another's. []

Email contains two important components which are also the content of the email: the header, and the body. Each header field contains a name, which is followed by a colon, which is also followed by the field value, and is used by the user agent. Message body, the content of the message from the sender to the receiver is transferred using the DATA command. Headers are sent, which is followed by a blank line, followed by the body. Each line transferred using the DATA command should be less than 1000 bytes.The user agent first takes what the sender wrote as a body, adds some headers and passes the result to the MTA. "The MTA then adds a few headers, and adds the envelope and sends the result to another MTA." []

Email that is network-based was exchanged on the ARPANET to the File Transfer Protocol (FTP) to the Simple Mail Transfer Protocol (SMTP) which is used today. SMTP communicates "delivery paramters" using the message envelope separately from the header and body in proccess of transporting e-mail messages between systems. []
