• 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 Enable STARTTLS on Port 25?

kgr

New Pleskian
Hello everybody,

I have a question regarding Port 25. Is it expected behavior that it doen't offer any TLS but only 465 and 587?
Is it somehow possible to activate STARTTLS on Port 25 without having any deeper issues?

I ask because I received an call today that my mail system can't be reached as it doesn't support TLS. (from another mailserver).
If I check on mxtoolbox and enter my plesk domain it says "Warning - Does not support TLS.", unless of course I force him to use port 587.

Best regards
