I accidently sent out sensitive personal information/material to the wrong address. When I queried the email address in Google, I found 7 sites with the same address. I have received delivery notifications that indicate they keep trying to send. I sent a reply to mailer-daemon@comcast.net asking them to DELETE DO NOT SEND. How do I contact Smart Zone Communications Center to confirm they will NOT send and they get deleted? I also need a way to contact Zimbra to confirm all emails are deleted do NOT send?
