Thanks for your reply.

I am aware of how to investigate the email header and get the IP address from there. However, i have another concern. I am looking for a way to find the IP address by sending a PM to this person, or by other means, through communicating with the Yahoo ID.

I need to confirm that the person who hacked my ID and is using it now, and the threat emails i was getting are from the same IP address. I was able to complete the first half of the task. I got the IP address through the email header. Now i need to get the IP address through his ID (by sending PM, or using netstat command, or any other mean possible).

If i am successful with this the second task, i will be able to confidently determine who hacked me, and sent me those threat emails. And i will be able to contact their ISP provider too.

If anyone has an idea, or any suggestion, please post it. I really appreciate your help!
