This tutorial will show you how to read the full email headers, also known as long headers or internet headers, from an email message in various email clients. An email collects information from each of the computers it passes through on the way to the recipient, and this is stored in the email’s Internet Headers. E-mail headers are helpful in determining the source of e-mail spoofing and in diagnosing many e-mail problems.
