But what was postfix reporting to the Appliance that tried to deliver to postfix?
search for "smtpd" lines in logs. According to your "unverified_recipient_reject_code = 550", it could be 550.
The 421 is what postfix got from the groupware. Not what it was reporting to the deliverer. Our setup is appliance -> Postfix -> Groupware. The appliance bounced several mails with a 550 5.1.0 Address rejected.
