Which email part is not typically included in header information?

The email content is not typically included in the header information. The header of an email provides routing and delivery information essential for the email's transmission, such as the sender's IP address, the time the email was sent, and the recipient's email address. These components are critical for identifying the origin and path of the email, as well as establishing its authenticity and timing.

In contrast, the email content refers to the actual message body that the sender intends the recipient to read. This content is stored separately from the header information and is not included as part of the header. Understanding the difference between these two segments is important in digital forensics, as investigators often analyze header information to trace the source and legitimacy of the email while treating the content as a separate area of inquiry.
