Go your Gmail Labs page and enable the “Sender Time Zone” feature. When the IP address is not available, you can determine the sender’s very-approximate location from the time-zone of the originating computer.

Mail and Hotmail include IP addresses in outgoing message headers but if John is sending an email address using Gmail, or Gmail for Google Apps, his IP address won’t be included in the message. When John sends an email message to Elizabeth, the IP address of the sender (John’s computer) is included in the header of the outgoing email message.
