The rejection always happens at the RCPT TO stage in those cases.
Thus it's called "smtpd_delay_reject".

Back in the dawn of Postfix I had this problem that a mailserver would
not accept a arejection at a prior stage. Thus it came back over and
over again. To be rejected over and over again.
Thus smtpd_delay_reject had been introduced, delaying the reject to
the RCPT TO: stage NOT MATTER what would have caused the rejection at
an earlier stage.
