It's telling you the issues, need to track them down (configs?)
Also, I found this to check dovecot:

As a general tip, try running dovecot directly in the foreground:
dovecot -F
The reason is the foreground will often output loadup error messages directly to the console, which will often allow you to quickly track down errors that are not usually logged (such as config parsing errors).

Everything I check about the errors seem to point to a configuration error.
