• 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.

Issue IDN Domain Mail Password Wrong

flth

New Pleskian
After updating to Plesk Obsidian the mail password on a IDN domain is always reported as wrong. Can't login, can't get emails on this domain.
Google and Plesk Knowledgebase didn't help.
Any suggestions?
 
Could you please be more specific? Any details from maillog at least?
 
Hello IgorG,

that's the weird thing, there is nothing than "permission denied" same on client as server. And it only affects the one IDN domain which work perfectly before in Plesk 17.

maillog says (I replace parts of the domain with xxx)

Code:
server authpsa[3023]: No such user 'info@rechtsanwälte-xxx.de' in mail authorization database
server courier-pop3d_ LOGIN FAILED, [email protected], ip=[ffff:82.83.xxx.xxx]

What I notice that there are .. instead ä. But tried the xn-domain as well without success.
