This should really be fixed. SMTPD_ACCESS_README (five times), ADDRESS_VERIFICATION_README and RESTRICTION_CLASS_README specify that "reject_unauth_destination is not needed here [= in smtpd_recipient_restrictions] if the mail relay policy is specified under smtpd_relay_restrictions".
Sorry: it's SMTPD_ACCESS_README, SMTPD_POLICY_README (four times), ADDRESS_VERIFICATION_README and RESTRICTION_CLASS_README.
