How to View Full Headers of an Email

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.

LMi uses these headers to diagnose email problems – whenever sending us a question about your email, please include the full headers.

Here are instructions for viewing the full headers in various popular email programs:
