Email headers can be thought of like envelopes for postal mail. They contain the electronic equivalent of addressing and postmarks that reflect the route of a mail from source to destination.The headers don't contain any personal information. At most, you can get the originating IP and the computer name that sent the email. The originating IP can be looked up to determine from where the email was sent..

Note: Microsoft's Hotmail service provides an extended header line called "X-Originating-IP" that contains the sender's actual IP address.
Note: Emails from Yahoo (if untampered) contain the sender's IP address in the last Received: entry
