The libz.so are for OpenSUSE and the QNap in the same directories withe the same permissions 

The macOS does not have a libz.so, this dovecot was build by macports.

All servers are running dovecot with the same user accounts.

At the moment I will look into this issue later and will try to authenticate without using

SSL.

On the MACs and openSUSE I authenticate using pam, the QNAP does not use pam

so I want to authenticate using a local password file, but I have problems to set it up correctly

I have changed it 10-auth.conf to use auth-passwdfile.conf.ext and created a password file called userdb.

I don’t know what else to change and what exactly should be in the userdb file.

The log only shows

Mar 20 23:52:45 auth: Debug: auth client connected (pid=6966)

Mar 20 23:52:45 imap-login: Info: Disconnected: Aborted login by logging out (no auth attempts in 0 secs): user=<>, rip=192.168.117.5, lip=192.168.117.2, session=<AhJNZ1T3GcDAqHUF>

I need to fix this first before I can enable SSL again.

Maybe I should open a new threat

My suggests to look for:

1. Are your other servers setups installed from "Entware for QNAP" too?
2. Do your other servers have libz.so* located under /opt/lib/ too?
3. Did you compare owner and permissions of every libz.so* file between
servers too?
4. Are other servers running Dovecot with same user account?

Have the dovecot settings the same on other servers and it works,
Dovecot is v2.3.18, installed from Entware for QNAP. Any help?appreciated.
