You could try using mail headers. That will show where the mail originated. You would have to work with the organization that own that IP from there though.

Most public email providers wouldn't allow you to spoof source address but you can do so with private mail systems. 

So if mail from Gmail etc, will be easy to proof its not authentic but not easy for other mailer unless you get inside assistance
