(If you do that, then you likely obviate the need to generate a new report back to that operator in the first place.) This to me is almost exactly the same thing as saying "Don't generate a bounce about a bounce", which has been part of SMTP for decades (it's a SHOULD NOT in 2821). I don't understand why you're saying it's appropriate in one but a non-issue in the other. -MSK
