Headers include identifying information such as the routing information of the message: the sender, recipient, date, and subject. Some headers are mandatory, such as FROM, TO, and DATE. Others are optional, but commonly used, like SUBJECT and CC.
Other headers may include good time stamps for when the message was sent, and the recipient time of all mail transfer agents that are associated with the message's delivery. Whenever a message is sent, each server or service that touches it (the MTA or Mail Transfer Agent) will leave a stamp.
The headers precede the information sent in the body of the e-mail.
