Email operates across computer networks, which today is primarily the Internet. Some early email systems required the author and the recipient to both be online at the same time, in common with instant messaging. Todays email systems are based on a store and forward model. Email servers accept, forward, deliver, and store messages. Neither the users nor their computers are required to be online simultaneously they need to connect only briefly, typically to a mail server or a webmail interface, for as long as it takes to send or receive messages. Originally an ASCII text only communications medium, Internet email was extended by Multipurpose Internet Mail Extensions MIME to carry text in other character sets and multimedia content attachments. International email, with internationalized email addresses using UTF 8, has been standardized, but as of 2.

OperationeditThe diagram to the right shows a typical sequence of events2. Alice transmits a message using a mail user agent MUA addressed to the email address of the recipient. The MUA formats the message in email format and uses the submission protocol, a profile of the Simple Mail Transfer Protocol SMTP, to send the message content to the local mail submission agent MSA, in this case smtp. The MSA determines the destination address provided in the SMTP protocol not from the message header, in this case bobb. The part before the sign is the local part of the address, often the username of the recipient, and the part after the sign is a domain name. The MSA resolves a domain name to determine the fully qualified domain name of the mail server in the Domain Name System DNS. The DNS server for the domain b. MX records listing the mail exchange servers for that domain, in this case mx. MTA server run by the recipients ISP. SMTP. This server may need to forward the message to other MTAs before the message reaches the final message delivery agent MDA. The MDA delivers it to the mailbox of user bob. Bobs MUA picks up the message using either the Post Office Protocol POP3 or the Internet Message Access Protocol IMAP. In addition to this example, alternatives and complications exist in the email system Alice or Bob may use a client connected to a corporate email system, such as IBMLotus Notes or Microsoft. Exchange. These systems often have their own internal email format and their clients typically communicate with the email server using a vendor specific, proprietary protocol. The server sends or receives email via the Internet through the products Internet mail gateway which also does any necessary reformatting. If Alice and Bob work for the same company, the entire transaction may happen completely within a single corporate email system. Alice may not have a MUA on her computer but instead may connect to a webmail service. Alices computer may run its own MTA, so avoiding the transfer at step 1. Bob may pick up his email in many ways, for example logging into mx. Domains usually have several mail exchange servers so that they can continue to accept mail even if the primary is not available. Many MTAs used to accept messages for any recipient on the Internet and do their best to deliver them. Such MTAs are called open mail relays. This was very important in the early days of the Internet when network connections were unreliable. However, this mechanism proved to be exploitable by originators of unsolicited bulk email and as a consequence open mail relays have become rare,3. MTAs do not accept messages from open mail relays. Message format editThe Internet email message format is now defined by RFC 5. ASCII data and multimedia content attachments being defined in RFC 2. RFC 2. 04. 9, collectively called Multipurpose Internet Mail Extensions or MIME. RFC 5. 32. 2 replaced the earlier RFC 2. RFC 2. 82. 2 in 2. RFC 8. 22 which had been the standard for Internet email for nearly 2. Published in 1. 98. RFC 8. 22 was based on the earlier RFC 7. ARPANET. 3. 1Internet email messages consist of two major sections, the message header and the message body, collectively known as content. The header is structured into fields such as From, To, CC, Subject, Date, and other information about the email. In the process of transporting email messages between systems, SMTP communicates delivery parameters and information using message header fields. The body contains the message, as unstructured text, sometimes containing a signature block at the end. The header is separated from the body by a blank line. Each message has exactly one header, which is structured into fields. Each field has a name and a value. RFC 5. 32. 2 specifies the precise syntax. Informally, each line of text in the header that begins with a printable character begins a separate field. The field name starts in the first character of the line and ends before the separator character. The separator is then followed by the field value the body of the field. The value is continued onto subsequent lines if those lines have a space or tab as their first character. Field names and values are restricted to 7 bit ASCII characters. Some non ASCII values may be represented using MIME encoded words. Email header fields can be multi line, and each line should be at most 7. Header fields defined by RFC 5. US ASCII characters for encoding characters in other sets, a syntax specified in RFC 2. Recently the IETF EAI working group has defined some standards track extensions,3.
