• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be 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.

Question Block outgoing email from domains that are not hosted.

New Pleskian
Hi,

I want to block all outgoing mail on our Plesk server that are using from email addresses that are not hosted on our website. Is there any simple way to achieve this in postfix? I've already tried updating smtpd_sender_restrictions, but that blocked all incoming email for some reason. Can anyone help me with this?

Kind regards,
Bas Milius
