That's not the default message, which is "Recipient address rejected:
Relay access denied."

Short of changing the source code, something like this should work:

main.cf:
smtpd_recipient_restrictions =
        permit_mynetworks,
        permit_auth_destination,
        permit_sasl_authenticated,
        check_recipient_access regexp:/path/to/file,
        reject

/path/to/file:
/^/ 550 Relaying denied. Proper authentication required.
