Remaining Anonymous
If you need to use an email account anonymously, you have to switch to a separate service like Hushmail (link in Resources). Hushmail allows you to use Tor when creating an account and while accessing it afterward. Keep in mind, though, to remain anonymous you must always use Tor software when accessing this account. If you access it just once with your real IP address, you could give away your anonymity.
Tracing Someone Else’s IP Address
If, on the other hand, you want to trace someone else’s Gmail IP address, look under the message’s full headers. If the message was sent from Gmail’s Web interface, the originator’s IP address will be hidden, but if she sent it through an email client such as Thunderbird, it’s possible to see her IP address.
