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:
Return-Path: [fake@address.com]
Received: from some.host.com (hostname [xx.xx.xx.xx])
by egr.msu.edu (8.9.3/8.9.3) with ESMTP id NAA23597;

From: Spammer [fake@address.com]
To: user@egr.msu.edu
Subject: My spam message!!
