temporary applied to the lack of reverse resolution, which is now
fixed. i wasn't querying the 554 code, just why murphy was messed up.

true. and it's not an excuse. it means that the provider is just
another one of those that doesn't know what they're doing. DNS is
bloody simple, it's amazing how many (influential) parties get it
wrong.

too much trouble. get your provider to do it right and your problems
are history.
