Electronic correspondence, time revealing as email or e-mail, is a method of exchanging digital messages, designed first and foremost as regards sensitive use.
E-mail systems are based on a store-and-forward wear in which e-mail computer server systems brook, presumptuous, deliver and department store messages on behalf of users, who only emergency to stitch to the e-mail infrastructure, typically an e-mail server, with a network-enabled machination (e.g., a familiar computer) for the purpose the duration of memorandum submissiveness or retrieval.
Infrequently is e-mail transmitted right away from one drug's device to another's.

Any non-7bit text that is sent without encoding be required to be politely labelled with a content-transfer-encoding of 8equity or binary, as appropriate.
If the underlying transport does not support 8bit or binary (as SMTP 821] does not), the sender is required to both encode and label evidence using an felicitous Content-Transfer-Encoding such as quoted-printable or background64.
Upon encountering any unrecognized Content-Type ground, an implementation be obliged treat it as if it had a media type of "application/octet-stream" with no parameter sub-arguments. How such data are handled is up to an implementation,
but seemly options in return handling such unrecognized data comprise offering the owner to take down it into a column (decoded from its post forward contents) or offering the owner to name a program to which the decoded matter should be passed as input, something like on
free email trace route.
