Extract the mail header in Mozilla Thunderbird

To be able to trace an e-mail the e-mail headers must be shown. Here you can follow the guide showing how to get mail header using Mozilla Thunderbird email application.

If you recieve some suspicious e-mail and want to report it to the email group or to the security department the unwanted e-mail must always be attached .

But there may be other situations where you should attach just the e-mail header, when it comes to troubleshooting, for example, for delayed emails.

Do like this:

  1. Start Thunderbird. Mark the suspicious e-mail and click on More. Click on View Source.
  2. Select and copy all text in the new window.
  3. Paste the text in the request you are about to send in.
