For whatever little it is worth, I would just like to say that I am
in general agreement with the proposition that it should be possible,
in the very short run, to reliably determine which, among a set a
email addresses, perhaps even numbering up to a million, are or are
not producing undeliverable bounce responses.

That having been said, I should also note that making this determination
with high accuracy is not nearly as easy as some folks might imagine,
due mostly to the utter lack of standards when it comes to the format
of undeliverable bounce responses.  And thus, some amount of manual
"eyeballing" may be involved with any attempt to do this at scale.
