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.
