• 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.

are you receiving any bounce back emails after sending an email to a certain email ID ? mostly probably you will find the exact error in the bounce back email only.
 
Hi,

Could you describe an environment of your installation? Is this Cloud Provider? Have you got a firewall between Plesk and the Internet? Could you connect via telnet from your Plesk to any mail server on the Internet via 25/tcp port? As an example: `telnet smtp.gmail.com 25`
