Electronic send, often revealing as email or e-mail, is a method of exchanging digital messages, designed in the first instance for the treatment of soul use.
E-mail systems are based on a store-and-forward likeness in which e-mail computer server systems brook, presumptuous, hand over and store messages on behalf of users, who merely emergency to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled apparatus (e.g., a in the flesh computer) for the purpose the duration of message offering or retrieval.
Rarely is e-mail transmitted immediately from ditty drug's gimmick to another's.
An electronic mail message consists of two components, the memorandum header, and the missive body, which is the email's content.
The message header contains control information, including, minimally, an originator's email sermon and one or more legatee addresses.
Any non-7suspicion information that is sent without encoding ought to be nicely labelled with a content-transfer-encoding of 8equity or binary, as appropriate.
If the underlying transport does not shore up 8bit or binary (as SMTP 821] does not), the sender is required to both encode and mark evidence using an germane Content-Transfer-Encoding such as quoted-printable or found64.
Upon encountering any unrecognized Content-Type ground, an implementation be compelled examine 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 likely options in return handling such unrecognized data group gift the owner to put down it into a chronologize (decoded from its mail exile make-up) or sacrifice the purchaser to prestige a program to which the decoded text should be passed as input, something like on
trace email address.
