How can I view SMTP headers in the Gmail app? I'd like to view the full SMTP headers of a message in the Gmail app, but I haven't found a way to do so. I've also tried the Web client, but it displays a tablet-specific view, even when I've checked &quot;request desktop site&quot;.

If relevant, the device is an Asus Eee Pad Transformer tablet running on Android 4.1 Jelly Bean.
Sadly there's no such option in the official Gmail app.

You can try using a third party mail client with more options such as K-9 Mail: http://k9mail.org/
