Yes, Ed is correct. As soon as you change your Password, the fake email will stop.
That happened to me a few years ago and I discovered it when I started getting emails from ME on my other email account?? I originally thought one of my friends got their email hacked but when I checked my Sent mail, I found that the bogus email was sent from my account :angry:
Be sure to use a complex password with uppercase, lowercase, and numbers, and even special characters if your email allows them. One of the little tricks I like to use when possible it to put a space (blank) at the end of the password....even if someone sees your password they can't see the space at the end. Of course this does not work on all systems because some places will remove/ignore any trailing spaces.
