You mentioned nothing of outbound mail in your diatribe, only inbound. That means you only perform half of your duties as a mail OP. There are numerous scenarios in which outbound mail will get deferred, sometimes for up to 5 days or more. Users have no clue there is a problem unless the receiving party is expecting the particular email and it doesn't arrive in a timely manner. By your own statement it would appear that you simply wait until the deferment times out and your user finally receives an NDR.

Other than that I agree absolutely with the rest, except to note that most of this monitoring can be done automatically with tools designed to *watch* for warning signs, and this *may* have been what Noel was silently referring to...
