If you're having difficulty with messages especially spam emails, viewing the message headers might help you track down the problem. The headers tell you where the email originally came from, and any other addresses it may have visited on its way to your inbox. Please follow the instructions below to view the message headers in your email program.

  1. Open the message in your Gmail inbox.

2. Click the down-arrow in the top-right corner of the message

3. Click the "Show original" link toward the bottom of the options box. The message will open in a separate window with the full message headers at the top.

4. A separate window will appear and will look similar to the one below.  This provides useful information for IT Providers and Google to see where the email is been sent from and can be blocked
