Centos 6.4, nginx, ispconfig, used the perfect server install. I have these errors: auth: Error: Can't open configuration file /etc/dovecot-sql.conf: No such file or directory Why is it looking there instead of /etc/dovecot/dovecot-sql.conf ? Nvm, dovecot.conf file had it wrong--I just don't know how that happened.
Create a symlink: ln -s /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf and then restart dovecot.
