I sent an email. It went to an old email address mistakenly, so it did not go through. I received a Mailer-daemon telling me it did not go through. Then it tried again, and sent a Mailer-daemon, then again, then again, and again. And it started again the next day. every few hours. I deleted the old email adress from my contact. HOW DO I STOP THIS EMAIL from from attempting to send over and over?
