How to find the IP address of the sender in Gmail Or Yahoo! mail

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.

First of all, the IP address is generally found in the headers enclosed beween square brackets, for instance, [129.130.1.1
