• 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.

SMTP Login Problem

I have just migrated from Ensim and cPanel to Plesk 8.1 and I am now getting complaints from users about not being able to log into SMTP with either password errors or the Server broke connection. Experimenting around if more then 4 users login at the sametime and a 5th tries to login the 5th one or higher will fail.

Coming from a Sendmail and Exim background I have no idea where to begin looking for a fix. Can anyone suggest a fix for this?
 
I have figured out what the problem was, maxperip was set to only 4 in imapd and pop3d.
