How to find the Email Header / EML in Thunderbird

What is an Email Header / EML file?

Every email that's sent has 2 parts, the body (what you see when you read the message), and the header. The header has information like the server the email came from, who sent it, what time it was sent, who the email was intended for. This information is important when you get a suspicious email or spam email that slips through the SPAM filter, as it can help find where exactly the email originated from.

Step 1 - (1) Select the email you want to find the header for then (2) Click View > Headers > All

Step 2 - Double click on the email

Step 3 - Press the Ctrl + U keys on your keyboard. You'll now see the header. Right click (or Ctrl + click on Mac) and click Select All. Then Right Click again and click Copy. Now you can close this window and paste the header into a text document or email to send to us to investigate for you.
