Dovecot configuration file errors [closed]

Solution 1:

Based on the error message, it looks like there might be a } character missing from the end of a previous service <name> { ... } block at or before line 82 in file /etc/dovecot/conf.d/10-master.conf.

There might even be multiple } characters missing, causing Dovecot to attempt parsing multiple service blocks as if they were settings for a single service.

If you are using some sysadmin automation tool (Ansible, Puppet, SaltStack, etc.), this might be an indication that something is wrong with the relevant configuration of the automation tool, e.g. a regular expression that matches more than it should and/or deletes the end-of-block } characters.
