• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Plesk 12.5 - Postfix without MDA

Vega80

New Pleskian
Hello,

is it possible to configure Plesk to use Postfix without Dovecot (or Courier)?

I want to use an external Mailhoster for all domains (mx is set to the external server), but all the e-mails from root or php should be send out directly from my server, so the SSMTP alternative ist not an option. For this I only need the MTA, but the plesk installer does not allow me to install Postfix without one of the two MDA options. And it is also not possible to disable the Courier service permanently via the panel, as it will be active again after a reboot. I don't want to have an unused service running for security and resource reasons.

I see some possibilities, but I would like to ask for an official way or at least some thoughts if can get some problems with my solutions:

1) "official way"?
2) Remove the execution rights for /etc/init.d/dovecot (will Plesk have any problems?)
3) No installation of postfix via plesk but manual installation of postfix or exim4. Should be no problem with php, but I guess it would not be possible to further use the e-mail notifications from Plesk, or does it use the default sendmail option of the system?

System: Debian 8, Plesk 12.5.30

Thank you!
