    Is there a way to find out where (City, State) a Yahoo email server is located or which one an email was processed through? I would assume there are several based throughout the US.

    Hello,

    Yes, through a combination of checking the full email headers and doing some traceroutes you should be able to figure out the general region that a mail server is located in. For example this header is taken form an email sent by xbox / Microsoft to a Yahoo account :

    Received: from 127.0.0.1 (EHLO mta.engage.xbox.com) (66.231.81.127)
    by mta1056.mail.ac4.yahoo.com with SMTP; Wed, 21 Sep 2011 17:49:04 -0700

    Usually a traceroute will give you some clue about the City and State from the reverse DNS names :

    That traceroute didn't have what I was looking for so I tried one of the IP geo location services and came up with Virginia.

    Richmond, VA might be the right answer, or it could be based off of the registration information for the network block.
