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: http://kb.parallels.com/Attachments/kcs-15646/MTA_presentation.pdf
and general postfix info related to TLS: http://postfix.state-of-mind.de/patrick.koetter/smtpauth/postfix_tls_support.html
main.cf 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.
