Dovecot can't find dovecot-sql.conf after 3.0.5.4p1 install
Dovecot does not work correctly after an install of ISPConfig 3.0.5.4p1. The error logs say that Dovecot cannot find dovecot-sql.conf which the install script created in /etc/dovecot. The simple hack is to copy dovecot-sql.conf to /etc by running the following line then restart Dovecot:
cp /etc/dovecot/dovecot-sql.conf /etc/dovecot-sql.conf service dovecot restart
