Dear All,
I have situation where in all External Mails were dropped by our smart host for particular period of time
From Exchange side they are not in queue and delivery report says delivered
I was working wit CISCO ESA support and according to them, there is no way messges can be retriggered or NDR can be genearted for te dropped messsages
I just want to know can we resend these messages from Exchange server or some how generate NDR for such external mails
