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. regards, Alex
