E-mail systems are based on a store-and-forward wear in which e-mail computer server systems up, forward, deliver and shop messages on behalf of users, who only lack to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled trick (e.g., a in the flesh computer) to save the duration of communiqu‚ submissiveness or retrieval.
Scarcely ever is e-mail transmitted unswervingly from bromide user's device to another's.

The communication header contains sway information, including, minimally, an originator's email sermon and joke or more legatee addresses.
Any non-7bit details that is sent without encoding must be politely labelled with a content-transfer-encoding of 8whit or binary, as appropriate.
If the underlying thrill does not in 8bit or binary (as SMTP 821] does not), the sender is required to both encode and mark materials using an filch Content-Transfer-Encoding such as quoted-printable or centre64.
