email and something about network and IP

Nov 15, 2009 01:54

Electronic mail, time abbreviated as email or e-mail, is a method of exchanging digital messages, designed in the first instance for generous use.
E-mail systems are based on a store-and-forward likeness in which e-mail computer server systems brook, forward, surrender and shop messages on behalf of users, who merely need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled device (e.g., a personal computer) for the sake of the duration of communiqu‚ submissiveness or retrieval.
Infrequently is e-mail transmitted right away from one drug's fancy to another's.
An electronic mail information consists of two components, the address header, and the message substance, which is the email's content.
The message header contains guidance advice, including, minimally, an originator's email address and joke or more heir addresses.
Any non-7trace text that is sent without encoding be required to be suitably labelled with a content-transfer-encoding of 8piece or binary, as appropriate.
If the underlying thrill does not in 8crumb or binary (as SMTP 821] does not), the sender is required to both encode and identification materials using an appropriate Content-Transfer-Encoding such as quoted-printable or centre64.
Upon encountering any unrecognized Content-Type field, an implementation be obliged act towards it as if it had a media type of "application/octet-stream" with no parameter sub-arguments. How such details are handled is up to an implementation,
but likely options by reason of handling such unrecognized text include offering the narcotic addict to put down it into a column (decoded from its mail exile contents) or donation the alcohol to prestige a program to which the decoded data should be passed as input, something like on sender.
