c was temporarily rejected for policy reasons. d should not be
retried. The DATA phase is only relevant for b.
And what about a ?
I agree d should not be retried.
There was one valid recipient. The 554 reply code is applicable to b only.
There were two valid recipients, and both did _not_ receive the message
because the data part is rejected.
Only c may receive the message, if the sender does retry and if by then
the receiver does accept the message.
