1. Email are accepted, forwarded and delivered by 2. What are the three components of email?

Question

Modern email operates across the Internet or other computer networks. Some early email systems required that the author and the recipient both be online at the same time, in common with instant messaging. Today's email system are based on a stroe-forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously; they need connect only briefly, typically to a mail server, for as long as it takes to send or receive messages. Histrociallly, the term electronic mail was used generically for any electronic document transmission. For example, several writers in the early 1970 s used the term to describe fax document transmission. As a result, it is difficult to find the first citation for the use of the term with the more specific meaning it has today. An internet email message consists of three components: the message, envelope, the message header, and the message body. The message header contains control information, including, minimally, an originator's email address and one or more recipient addresses. Usually descriptive information is also added, such as a subject headed field and a message submission date/time stamp.
