E-mail Header

E-mail Header: The E-mail Header contains some user as well as some technical information about the e-mail. Generally, this includes: the list of machines through which the e-mail has passed; date and time stamps from the machines through which the mail has passed; the name and version of the client program that created the e-mail; a ‘Message-ID' that uniquely identifies the e-mail from the sending machine's point of view.
