• 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.

Resolved Obsidian plesk centos 7 - roundcube error 535 smtp

Pecnet

Basic Pleskian
Hello,

I'm on centos7 and plesk with Obsidian, I have a SYS server at OVH and a webpro license.
I configured the settings of my plesk but I have a problem when I want to send a message with roundcube I have this error ->

I have this message

SMTP error (535): failure during authentication.

With the old version of plesk Onyx I did this manipulation and it works, now I tried with Obsidian and it doesn't work

see here

-> Resolved - Roundcube - SMTP 535 error - Plesk 17.8.11 #2

I also tried this link but it doesn't work

-> Unable to send an email from Plesk server: SMTP Error (535): Authentication failed

Have any idea how I can fix this?

thank you

well you allready used the 2 most common workarounds, so maybe there are more details in the logfiles like /var/log/plesk-roundcube
