To see where an e-mail started and where it's been, check the headers. You can check suspicious e-mails on OSX's "Mail" client by clicking on the "long headers" button in your toolbar, or going to the main menu and then View>Message>Long Headers. Other people who have received something supposedly from you can compare an e-mail ACTUALLY sent from you with one of the suspects and see where it came from and where it traveled on its way (what servers and IP addresses it passed through) on its way to them. It can also help you backtrack and let the real sender know they've got a problem. Ted.
