How to Expand Your Email Headers

Sometimes you may need to view the full header of an email message to get more info about the routing or sender, or to report a problem. Below is information on how to view these headers in popular email applications.

 

Most e-mail programs display partial headers, which typically show the basic to/from information, the date, and a subject line. Full or extended headers (raw headers) have additional fields, including information on how the message reached you. They are included with each e-mail, but are not always visible.

The following instructions for viewing full headers were contributed by RootsWeb users, and verified when possible with instructions offered on the help pages of mail programs and SpamCop.
