Electronic mail email or e-mail is a method of exchanging messages " mail " between people using electronic devices.

Invented by Ray Tomlinson , email first entered limited use in the s and by the mids had taken the form now recognized as email. 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. Today's 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. International email , with internationalized email addresses using UTF-8 , has been standardized, but as of it has not been widely adopted. An email message sent in the early s looks very similar to a basic email sent today.

Historically, the term electronic mail was used generically for any electronic document transmission. For example, several writers in the early s used the term to describe fax document transmission.

Electronic mail has been most commonly called email or e-mail since around , [6] but variations of the spelling have been used:. An Internet e-mail consists [24] of an envelope and content; the content in turn consists [25] of a header and a body. Computer -based mail and messaging became possible with the advent of time-sharing computers in the early s, and informal methods of using shared files to pass messages were soon expanded into the first mail systems.

Most developers of early mainframes and minicomputers developed similar, but generally incompatible, mail applications. Over time, a complex web of gateways and routing systems linked many of them.

For a time in the late s and early s, it seemed likely that either a proprietary commercial system or the X. The diagram to the right shows a typical sequence of events [28] that takes place when sender Alice transmits a message using a mail user agent MUA addressed to the email address of the recipient. 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. Internet email messages consist of two major sections, the message header and the message body, collectively known as content. 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 specifies the precise syntax. Informally, each line of text in the header that begins with a non- whitespace 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.

Email header fields can be multi-line, and each line should be at most 78 characters long and in no event more than characters long. Such addresses are supported by Google and Microsoft products, and promoted by some governments.

The message header must include at least the following fields: Common header fields for email include: Note that the To: The actual delivery list is supplied separately to the transport protocol, SMTP , which may or may not originally have been extracted from the header content. In the same way, the "From: Some mail servers apply email authentication systems to messages being relayed. Data pertaining to server's activity is also part of the header, as defined below.

SMTP defines the trace information of a message, which is also saved in the header using the following two fields: Other fields that are added on top of the header by the receiving server may be called trace fields , in a broader sense.

In some countries, several encoding schemes coexist; as the result, by default, the message in a non-Latin alphabet language appears in non-readable form the only exception is coincidence, when the sender and receiver use the same encoding scheme. Therefore, for international character sets , Unicode is growing in popularity.

Most modern graphic email clients allow the use of either plain text or HTML for the message body at the option of the user. HTML email messages often include an automatically generated plain text copy as well, for compatibility reasons.

Advantages of HTML include the ability to include in-line links and images, set apart previous messages in block quotes , wrap naturally on any display, use emphasis such as underlines and italics , and change font styles. Disadvantages include the increased size of the email, privacy concerns about web bugs , abuse of HTML email as a vector for phishing attacks and the spread of malicious software.

Some web-based mailing lists recommend that all posts be made in plain-text, with 72 or 80 characters per line [53] [54] for all the above reasons, but also because they have a significant number of readers using text-based email clients such as Mutt. Some Microsoft email clients allow rich formatting using their proprietary Rich Text Format RTF , but this should be avoided unless the recipient is guaranteed to have a compatible email client.

Messages are exchanged between hosts using the Simple Mail Transfer Protocol with software programs called mail transfer agents MTAs ; and delivered to a mail store by programs called mail delivery agents MDAs, also sometimes called local delivery agents, LDAs. Accepting a message obliges an MTA to deliver it, [56] and when a message cannot be delivered, that MTA must send a bounce message back to the sender, indicating the problem. Users can retrieve their messages from servers using standard protocols such as POP or IMAP , or, as is more likely in a large corporate environment, with a proprietary protocol specific to Novell Groupwise , Lotus Notes or Microsoft Exchange Servers.

Programs used by users for retrieving, reading, and managing email are called mail user agents MUAs. Mail can be stored on the client , on the server side, or in both places. Standard formats for mailboxes include Maildir and mbox. Several prominent email clients use their own proprietary format and require conversion software to transfer email between them.

Server-side storage is often in a proprietary format but since access is through a standard protocol such as IMAP , moving email from one server to another can be done with any MUA supporting the protocol. Mail, that performs the same tasks. Upon reception of email messages, email client applications save messages in operating system files in the file system.

Some clients save individual messages as separate files, while others use various database formats, often proprietary, for collective storage. A historical standard of storage is the mbox format. The specific format used is often indicated by special filename extensions:. Mail Collector Collect all your emails from different accounts in one place.
