    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.
