Bingo! That's what I would like to do! Send a Postfix error to some dork
that thinks THEIR email server is configured properly is useless; what I
am looking for is a detailed explanation of the causes for such errors.

Been there, tried that - the response is typically "we don't have a
problem - it's YOUR problem because YOUR server is rejecting OUR email".

Hence the discussion on a more definitive source of the problem.
