• 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.

failure notices sent on properly delivered mails

A number of our clients are reporting that they receive a failure notice, entirely randomly, when sending to a valid recipient.

They receive the failure notice, which lists all the failure notices on the server (typically sent to postmaster@), despite their email being properly delivered.

Anybody else experiencing this issue? How can I solve it?
