Just be careful that you don't put too much faith in that information in the headers... if the sender knew what they were doing, it would be fairly trivial to fake that information.

Also, it could very well have been sent from his machine... if his machine is compromised, someone other than him could have hacked into it and sent that email, and would probably have access to all of the other emails on that system (and therefore the detailed information you're referring to).


Case in point: In one of my old apartments, we were all wired for high-speed internet. One of the neighbours had his box hacked, and was saturating all of our bandwidth with spam, warez ftp servers, etc.

I ended up hacking into the box and finding his resume, and called him at work to ask him to please fix his box as it was hacked, yada yada.

He was totally unaware that it had happened, other than "it felt slow for the last few days". He was also freaked that I'd been able to get into his personal info on it. He then had me over for beers to clean it up and secure it for him.
