• 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.

I want to insert the List_Unsubscribe header in Postfix so that it can also be used by clients like Thunderbird and not only by WebMail Roundcube.
How can I do it?
 
I want to insert the List_Unsubcribe header too. I am also using Thunderbird. Please let me know if you find any solution!
 
You'll find plenty of step-by-step guides with a Google search like "list_unsubscribe postfix".
