Plesk if you have something else blocking the port:

lsof -i tcp:106

Hi Martin,

Nope, lsof -i tcp:106 returns nothing. And both OS & Plesk is fresh installed, so no other application is occupying the port.

I guess it is related to IPv6 is not enabled, so the poppassd cannot bind [::1]:106 , can Plesk detects and don't use IPv6 for poppassd if IPv6 is not enabled?

To put it simply, it's important to make sure that IPv6 is set up correctly on your server. If your server doesn't support IPv6 or you're not planning to use it, you might want to change the settings for the poppassd service so that it listens on the IPv4 address, which is 127.0.0.1. This is just a suggestion based on the information you've provided, and it might help resolve the issue you're facing with the poppassd.socket service.
