When you think of traditional mail, the two parts are easy to see. With paper mail, there is the envelope with the address, stamp, and postal information on it, and the letter or other paperwork inside.
With email, it’s similar. There are also two separate parts that make up a single email message. There’s the header, which contains control information and other data, and the body of the message, which contains the sender’s text, as well as attachments and other components.
The header section of an email message acts like the envelope of a written letter. This section contains information about the sender, the recipient, and the route the email takes to the recipient’s inbox. It also contains various necessary authentication details. The header always precedes the body of an email.
