Yeah, google can if you get a court order for it. A complete header might be a little helpful if it were forwarded but 99% of the time when it's a free e-mail account it's not traceable without a supboena.
If you want someone to find out who actually sent that it is possible using context clues, etc.... But it would all be circumstantial. If you don't want to post the email, forward it to me at [email protected] and the backstory. I will see what I can find, no promises though.
I have my windows open, started to smell like someone shit on my window ledge, realized it was the pungent stench of socialism. Sorry if there is any typos in this post, hard to read shit through this gas mask.
