Dovecot error

[Declan1]

It appears I have somehow blown out the Dovecot function.  Logging into an email account produces this error message:  Connection to storage server failed.

Also, if I restart Dovecot with service dovecot restart, these messages eventually appear:
Dec 16 15:22:32 admin.rstinternetmarketing.com systemd[1]: Started Dovecot IMAP/POP3 email server.

Dec 16 15:22:32 admin.rstinternetmarketing.com dovecot[10726]: master: Dovecot v2.3.7.2 (3c910f64b) starting up without any protocols (core dumps disabled)

Dec 16 15:27:42 admin.rstinternetmarketing.com dovecot[10741]: auth: Fatal: No passdbs specified in configuration file. PLAIN mechanism needs one

Dec 16 15:27:42 admin.rstinternetmarketing.com dovecot[10726]: master: Error: service(auth): command startup failed, throttling for 2 secs

There must be a file, configuration or otherwise, that got messed up but I haven't been able to find it.

Thank you!

Your Dovecot error occurs because no authentication database is configured. To fix it:

1. In
   
   Code:

   /etc/dovecot/conf.d/10-auth.conf
   , define a
   
   Code:

   passdb
   , e.g.:
   
   Code:

   passdb { driver = pam }
   or for SQL:
   
   Code:

   passdb { driver = sql; args = /etc/dovecot/dovecot-sql.conf.ext }
2. Ensure
   
   Code:

   protocols = imap pop3
   is set in
   
   Code:

   dovecot.conf
   or
   
   Code:

   10-ssl.conf
   .
   
3. Reload Dovecot:
   
   Code:

   sudo dovecot reload
   .
   
4. Check logs for remaining errors.
   

This should resolve the authentication and “connection to storage server failed” issues.
