I think I've come to a dead end as I think the IP is bt server address.
Can anyone confirm this or point me in the right direction of finding the origin of the email please?
Thanks for your question evejames.
I removed the image you had linked to your post because it had the potential to harm the sender of the email through the release of their personal information such as name and email address.
If you want to trace an email, post only the info needed to do that, usually the x-originating IP. and possibly the mail server it was sent from.
NOTE: You will not be able to trace the email to a specific person or computer without intervention from a legal authority and they won't take action without some type of legal motivation such as a physical threat against someone.
