Here's the entire header (apart from my name redacted); can't see anything of interest but YMMV:

Me neither.
I thought gmail included client's IP in the headers, but apparently that's not the case.

Sorry email reacts completely different than you would think. You will never get the IP address of the mail client (Were the hell is he at) unless the sender runs their own email server from home.

Your email client or web interface logs into the server and the server handles everything. The address at the top 10.xx.xx.xx is a non-routable address along with 172.16.xx.xx and 192.168.xx.xx

A non-routable address implies that once the IP hits the firewall, the firewall converts the packet to a public address and then sends the packet along.

Try it from home. I have 2 email accounts, and sent a test message from one to the other. My gateways were Washington state (outlook.com) and Northern New Jersey (comcast.net); both of my email accounts.
The data center for my ISP is about 20 minutes from the house and that was the address given in the email.

The gmail gateway used is located in France, near Luxembourg. Try this utility: http://www.ipligence.com/geolocation

Can you tell I do this for a living?
