Can you discover what location an email has been sent from, from an IP address?
From the “Received” headers in an email, it’s easy to tell which computer first dispatched an email. Unfortunately tracing the sender isn’t that simple. Millions of emails a day are sent from compromised computers without their owners knowing about it. Hidden processes controlled from afar send email after email, and that computer’s address will appear as the email’s originator. If I were you, I’d ask to see the evidence against you, and then show it to someone who knows about such things. I would recommend against the advice to traceroute (or tracert) to the originating host. It won’t tell you as much as looking up the IP address on http://www.arin.net/whois/ and may draw attention to yourself if that address turns out to be compromised.
