email identity

[mammu]

My bro got some nasty emails...maybe someone from his staff.
I want to know if is there any way to find out IP of the sender or track identity or anything which leads to him.
Its a yahoo email id.

I was thinking can we track IP from email and see the location of that guy from google earth with the help of IP or any other method.

Help will be appreciated.

It's very easy to fake your IP address or even use a zombie machine, but you can try by using a program such as this:
