I attempted to send a email to the incorrect email address one time so I received a "delivery status notification (failure)". Now that i sent that email one time, I am receiving Delivery Status Notification (Failure) emails every 30 minutes or so. It will not stop and i have tried deleting all the emails sent. I only sent it one time, but when i go into my sent box i see that it keeps trying to send the same incorrect email. Please help me stop this.
