The use of a status of 4xx in conjunction with an extended status of
5.something seems to be absurd, no?

The original question appeared to be trying to use an unqualified
domain in their envelope sender - doesn't look good to me.

Fair comment, but I can't believe that applying one's normal retry
strategy in response to the 4xx status is going to be useful. As
such, I'd tend to rate this response as a rogue. The status they
returned *should* have been 5xx, in my view.
