What is IP address?

IP stass="answer">No. Email address is not associated with any geographical or IP address. Mail servers can usually be accessible from anywhere in the world by any number of people who know the password. Email service providers do know from what IP some certain email was sent but this information is normally kept private and is not legally obtainable (unless you have a warrant from court to obtain this information and the mail servers are in the country where this warrant can be enforced)
