We've talked about changing bounce handling so that all bounces of any
kind are handled similarly. They'd have a threshold over which the
action would occur. By default, the address would be disabled, and
then some future attempts would be made to contact the user. If they
can't be reached after N number of attempts, maybe they'd be removed.
That way if a user is temporarily unavailable (for whatever reason),
they wouldn't get immediately nixed, and they'd have an opportunity
later to re-enable themselves.
