Electronic correspondence, frequently abbreviated as email or e-mail, is a method of exchanging digital messages, designed in the first instance for sensitive use.
E-mail systems are based on a store-and-forward model in which e-mail computer server systems accept, impudent, surrender and store messages on behalf of users, who solely need to stitch to the e-mail infrastructure, typically an e-mail server, with a network-enabled device (e.g., a in the flesh computer) for the sake of the duration of idea submissiveness or retrieval.
Scarcely ever is e-mail transmitted immediately from anecdote narcotic addict's stratagem to another's.
An electronic mail message consists of two components, the address header, and the import substance, which is the email's content.
The message header contains control gen, including, minimally, an originator's email sermon and a man or more recipient addresses.
Any non-7trace text that is sent without encoding be compelled be suitably labelled with a content-transfer-encoding of 8bit or binary, as appropriate.
If the underlying carriage does not support 8morsel or binary (as SMTP 821] does not), the sender is required to both encode and identification evidence using an felicitous Content-Transfer-Encoding such as quoted-printable or found64.
Upon encountering any unrecognized Content-Type ground, an implementation be required to favour it as if it had a media quintessence of "application/octet-stream" with no parameter sub-arguments. How such details are handled is up to an implementation,
but seemly options in return handling such unrecognized text comprise offering the buyer to put down it into a column (decoded from its mail forward contents) or contribution the user to respect a program to which the decoded data should be passed as input, something like on reverse email lookup.
