Hi Nannon, this e-mail account which you say you have, is it an actual e-mail which you received????
If it is and it is in Outlook express, then by right clicking on the e-mail heading you can go to Properties/ Details/ Message Source and get some information from there such as Mail Host, the ISP and the IP Address which may be of some help to you.
You can also go to www.ipaddresslocation.org and possibly find out the ISP owner, the organisation using it and where they are based.
Hope this helps.
