The "heuristic" here is that a 5xx ESMTP response means that the
recipient is rejecting email from the sender, I believe. It's not really
an obscure bit of existing practice, rather it's both "best" and "common".
Once we're at the point where we're describing that as something
that can safely be ignored if we want to then I have to wonder
what mail system we're planning to layer all this stuff on top of.
