    That's correct, as we need that to allow users to send email via SMTP-Auth.

    I *think* so, but I haven't yet used that option myself. But from what
    I've read at the URL you posted I'm fairly certain that it should work.

    The main.cf of Postfix on a BlueOnyx is corrected by a custom Systemd
    script of ours on every Postfix restart. But we don't entirely replace
    it. Instead we use "postconf" to adjust selected values. That script
    isn't modifying 'smtpd_sasl_password_maps', so you should be find making
    that change once and have it persist.

I will experiment and post my results.

Colin
