Hi Team, I'm facing difficulties with the new installation. Last week, when I installed the process went smoothly. But today when I tried, the installation completed with error. Yes. The Dovecot services were not installed during the installation. So there is no dovecot folder in the /etc folder to grab the dovecot.conf file. When I tried to install dovecot from the repository, the service runs, but it gives authentication error and Cant connect to the server error sometimes. Rainloop didn't work. Outlook didn't work. Postfix works fine. Please help me with the issue.
OS: Ubuntu 20.04.2 LTS GNU/Linux 5.4.0 x86_64)
Hosting: A2 Unmanaged VPS.
Kindly do the needful.
