Complete headers provide more information on the origin of a message and are a useful tool for tracking and stopping spam e-mail. Most e-mail readers only show the To: and From: headers, which can be easily forged. The complete message headers will look something like this:
Received: from some.host.com (hostname [xx.xx.xx.xx])
