Dovecot auth Error

Hi everyone,
I just set up ISPConfig 3.2.9p1 using the perfect server single serve manual which uses a script. All went well until I tried to set up an IMAP/PoP3 email account or login to Roundcube after adding the email account to the ISPConfig control panel. I get the errors below from the mail.log.

Current Dovecot config

Code:

$ dovecot -n
# 2.3.16 (7e2e900c1a): /etc/dovecot/dovecot.conf
# Pigeonhole version 0.5.16 (09c29328)
# OS: Linux 5.15.0-72-generic x86_64 Ubuntu 22.04.2 LTS
# Hostname: mailserver.domain.

I created an email account on the control panel first before testing. I checked the phpmyadmin table and saw the email account there as well. I also double-checked for typos and there were none.

I used the auto-installer, no files were manually edited. First time running it on freshly installed Ubuntu 22.04

 

I found the problem. During set up of the email domain I selected the wrong server. I have got multiserver setup for 2 name servers and single server set up for mail, web and database so it automatically selected the primary name server. Thanks for your help.
