Is there a source for information on working out where an email has come from? I sometimes get spam sent back to me that I supposedly sent out (though I didn't) and I want to see if I can track down the real sender.
There are lots of resources that will help you read and understand email headers, and the one I'd recommend is from the Stop Spam website (www.stopspam.org/email/headers.html).
