Wouldn't it be better to put $reject_unauth_destination closer to
the top of the restriction class: i.e. after $check_recipient_access?
and then $permit_mynetworks after that?
Like so:
smtpd_recipient_restrictions =
check_recipient_access hash:/etc/postfix/relay_domains,
reject_unauth_destination,
permit_mynetworks,
...
