You can't be sure of finding the exact physical location. You can a rough idea in some cases:

(1) Step 1 is to get the correct IP address. If you are not adept at reading email headers, chech these links:

   http://www.stopspam.org/email/headers.html
   http://itim.tamu.edu/htmlfs/mailheaders.shtml

(2) Go to http://www.arin.net/ and enter the IP address in the field at the top right and click on "Search Whois"
 This will either give you some information about the name and location of the controlling body, or in the case of European or Asian or other non-US addresses, give you the address of another more specific site where you can repeat the Whois search.

(3) Do a DNS lookup on the IP address. Open a Command Window and type:

   > nslookup #.#.#.#    

  (assuming you've Windows) and it may give you the name of the organization that the IP belongs to.

(4) These days there are some sites that automate the above process, i.e. you enter the IP address and they try to give you a location, even a map. e.g. try http://www.networldmap.com/TryIt.htm
