When installing the control panel from scratch with a fully clean OS and newly installed, I released that error of the title. So far I do not understand why it happens.

Check to see if dovecot was installed and surprise. It was not installed. Does someone explain to me?

Run sudo yum install dovecot -y on CentOS or sudo apt install dovecot-imapd dovecot-pop3d on Ubuntu
