Figuring out Plesk and postfix interaction with PMAS

All works except email submission via port 587 [followup: was failing because ptsmtp was listening to 587 and it shouldn’t].

Plesk MTA info:

and general postfix info related to TLS: has:

smtpd_sender_restrictions = check_sender_access hash:/var/spool/postfix/plesk/blacklists, permit_sasl_authenticated

so nothing funny there with Plesk.

smptd.conf has:

saslauthd_path: /var/spool/postfix/private/plesk_saslauthd

so maybe the question is what does plesk_saslauthd do?  Ultimately didn’t have anything to do with the problems but someday would like to understand why Plesk doesn’t seem to do what’s documented for postfix.
