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.
I am unable to send out any email. I get an error: "the connection to the server was interrupted". I am able to receive email just fine, but can not send at all. Any suggestions on what I can do?
I have cleared the mail queue which had 830 messages that had not been processed and I have restarted the server. What is strange is that I can send email just fine through webmail, but cannot do so through Outlook on two separate computers... Any suggestions?
