This has absolutely never happened and it won't because I backed out the LSV$DNT I put in back on the 2nd. I have observed 2 instances of the DNS we use getting into this state for 10 or 15 minutes before they can shut it down or fix it. This over the last couple of years, both before we supported auto-delete. The question was that IF it happened again during the window after a sucessful delivery to a list if it could result in all the smtp users on the target list getting wiped out at one shot.
