There are at least two of these lines per e-mail header since one server is used to send and one is used to receive. Received: Received lines are generated by the mail servers that are involved in the transfer. The delivered e-mail address is identical to the one that the server receives via the “envelope-from” information. Return-Path: When available, this line is almost always at the beginning and gives the mail server a return option in case delivery is not possible. The sender should make it clear to the reader what the e-mail is regarding.Įxample: Cc: Re: Your appointments for the coming year
Subject: The subject lets the recipient know what kind of content to expect. It could even be the case that your e-mail address does not even appear in this line.Ĭc: This optional information contains the address(es) of one or several recipients that are to receive a copy of the e-mail.Įxample: Copy-recipient, Copy-recipient 2
The information does not have to correspond with the “envelope-to” information that is transmitted by the transfer protocol. To: In this e-mail header line you find the name of the recipients separated by commas. If the technical sender is not the writer of the e-mail, this will be mentioned in the additional “sender” line. There are also e-mail clients that allow several senders. From: This is the information about the sender or writer in the form of an e-mail address.
