When i receive a mail in yahoo, from message header, i get IP address. But the location is that of ISP and not that of the sender.

Is there any way to find the IP address and or location of the sender?

I read in a book that mostly IP addresses are dynamic. Even if  i find an IP address, if i don't trace the person immediately, then there are greater chances of selecting another person is high. isn't it?
