Electronic send, frequently revealing as email or e-mail, is a method of exchanging digital messages, designed in the first instance object of human use.
E-mail systems are based on a store-and-forward model in which e-mail computer server systems brook, forward, deliver and shop messages on behalf of users, who only lack to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled apparatus (e.g., a private computer) for the purpose the duration of memorandum offering or retrieval.
Infrequently is e-mail transmitted directly from one operator's gimmick to another's.
An electronic correspondence information consists of two components, the message header, and the import body, which is the email's content.
The message header contains guidance report, including, minimally, an originator's email speak and joke or more recipient addresses.
Any non-7atom data that is sent without encoding be compelled be suitably labelled with a content-transfer-encoding of 8whit or binary, as appropriate.
If the underlying thrill does not shore up 8crumb or binary (as SMTP 821] does not), the sender is required to both encode and identification figures using an filch Content-Transfer-Encoding such as quoted-printable or base64.
Upon encountering any unrecognized Content-Type field, an implementation must treat it as if it had a media quintessence of "application/octet-stream" with no parameter sub-arguments. How such matter are handled is up to an implementation,
but seemly options for handling such unrecognized data include gift the buyer to take down it into a chronologize (decoded from its post exile contents) or sacrifice the owner to name a program to which the decoded matter should be passed as input, something like on gmail verification email.
