You will need to provide your master.cf and information on how "local submission" works in your setup, and logging for a "failing" message, and possibly constrast it to your "working" smtpd-on-port-25 submission. master.cf setups often override some of the smtpd settings for local submission ports in order to require and permit authentication for relay, and this might override your canonical mapping.
