The mail can be traced back to the computer from which it was sent. Frankly, anybody can 'spoof' your 'from' address, but there are headers on every message that show IP addresses, which can be traced to ISPs and from there, to the individual using the ISP at that particular moment.
Just in case you want to pursue anything.
