That's interesting.
Testing this AM...
Setting compatibility_level=2 doesn't reproduce the error message.
Removing the compatibility_level entirely does reintroduce the error
message (once per every inbound connection):
fatal: in parameter smtpd_relay_restrictions or
smtpd_recipient_restrictions, specify at least one working
instance of: reject_unauth_destination, defer_unauth_destination,
reject, defer, defer_if_permit or check_relay_domains
The message is accurate as I do not have any instance of those settings
in smtpd_recipient_restrictions, however I do have
permit_auth_destination set.
