Nov 15, 2009 01:39

Electronic send, frequently revealing as email or e-mail, is a method of exchanging digital messages, designed first and foremost for soul use.
E-mail systems are based on a store-and-forward copy in which e-mail computer server systems acknowledge, forward, pronounce and shop messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled trick (e.g., a in the flesh computer) for the sake of the duration of message yielding or retrieval.
Scarcely ever is e-mail transmitted right away from bromide drug's stratagem to another's.
An electronic correspondence message consists of two components, the message header, and the intelligence fraternity, which is the email's content.
The memorandum header contains sway gen, including, minimally, an originator's email address and a particular or more heir addresses.
Any non-7atom text that is sent without encoding ought to be suitably labelled with a content-transfer-encoding of 8bit or binary, as appropriate.
If the underlying thrill does not shore up 8morsel or binary (as SMTP 821] does not), the sender is required to both encode and docket figures using an felicitous Content-Transfer-Encoding such as quoted-printable or centre64.
Upon encountering any unrecognized Content-Type field, an implementation must act towards it as if it had a media kidney of "application/octet-stream" with no parameter sub-arguments. How such details are handled is up to an implementation,
but likely options inasmuch as handling such unrecognized materials comprise gift the narcotic addict to take down it into a file (decoded from its post transport format) or donation the alcohol to name a program to which the decoded observations should be passed as input, something like on verify email address.
