How To View Full Email Headers in GMail

Sometimes you need to view the full email headers to understand whether an email sender information or other details is faked or to even debug your MTA (my situation). Unlike other email clients GMail doesn’t give you an intuitive way to get the full headers. Nevertheless when you know it, it is very simple. Here are the steps:

1. Open the email in Gmail
2. Click on the combo-box titles Reply and select Show original. That’s it!

The email with full header details is displayed in a separate window / tab (depending on your browser configuration).

(okay, yes, nearly four years later…)

Found info about headers on Google’s help page, but not how to actually view them in entirety. Not intuitive, indeed!
Thanks much for this!

Hello All,

I believe I found a way for the Gmail …”show details” to stay always enabled.
I could not find any tip , trick or answer on the Web when I searched and searched for an answer, so by luck I discovered it and probably it was not intended for this (the ‘Show Details’ to stay enabled) but fortunately I got what I needed from this discovery, here it is:

Click on the very bottom of your screen, click “basic HTML” …and this will flash your screen turning it to a similar screen but in mode of “basic HTML” which will allow you, once you open any of your inbox mail to see automatically the list of all receipients and their addresses (SO, NO need here to click ‘Show details’ anymore!)

Then to go back to original Default, you can click on “Standard HTML”
