Question

Undeliverable messages get sent to sender after IIS is restarted

Asked by: timbone101

I have a law firm client that got a virus and ended up on a blacklist.  After cleaning things up and getting off the blacklists, we have had a few minor issues with some emails not getting delivered.  Employees would send emails and the recipient would either get it after a very long delay or many times not at all.  The problem is the sender would not always get a bounceback NDR telling them the message was not delivered.

Over the weekend, I was installing a new app that required a restart of IIS.  Immedately after restarting IIS, a whole bunch of employees got NDR notices on messafges they sent back in June and July.  My question is why would they be getting these NDR's now only after IIS was restarted?  Needless to say, a few attorneys were pissed that they did not get informed their messages did not reach their intened recipients.
