Instead of kvetching about ADSP, you might tell the list owners that their

Mailing lists are on higher ground, since they are not introducing the

When we let existing heuristics dictate what we can design on the net, then
we have
failed. Heuristics by their nature are then things that need to deal with
their own
shortcomings. The problem here is not with ADSP. It's bad assumptions made by
heuristics.
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.
Cheers,
Steve
