    In this post i will show you How to find the IP address of the sender in Gmail, Yahoo! mail or Hotmail. When you receive an email, you receive more than just the message. The email comes with headers that carry important information that can tell where the email was sent from and possibly who sent it. For that, you would need to find the IP address of the sender. The tutorial below can help you find the IP address of the sender. Note that this will not work if the sender uses anonymous proxy servers.

    What is email Header?

    Every message contains a series of header lines that instruct mail servers where to deliver it, tell mail readers how to process its content, and provide a record of the path taken by the message from its source to its destination. Message headers fall into five classes. The basic addressing information is contained in the From and To lines, and information about the content is contained in the Subject line and those that begin with Content. The path taken from the sender through to delivery is recorded in the Received lines, and the unique identity of this message is captured in the Date and Message-ID lines. Ancillary information that might be useful for the email client is usually found in headers that begin with X-. The specific headers can vary widely according to the email client that was used to create the messages.
