How do I forward full email headers?

If you report abusive, malicious or otherwise unsolicited email to the University, the IT Security team may request that you forward the email to them with full headers. Each email you receive contains information about where the message came from and which computers it went through on its way to your mailbox. This information, contained in the message's headers, is usually masked from your view. When you display full headers, you're telling your email program to restore this information, which can be used to trace the email back to its source.

These instructions provide assistance in forwarding email with full headers from a variety of email programs.
