• 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 SMTP only port 25 without encryption working

New Pleskian
Hi,

first time I configured a Domain and an E-Mail in my new Plesk Server, not much experience with Plesk and administring Servers here.

Through my E-Mail client I can only login to Plesks SMTP through Port 25 without encryption, any other Port / encryption does not work. What do I have to do to be able to use encryption (I am using the Gmail webclient as E-Mail client).
