Dovecot2 install on CentOS (6) broken
The installer for CentOS 6.x creates the dovecot.conf for Dovecot 2 (currently available version through CentOS repos is 2.0.x) in the wrong locastion.
dovecot.conf and dovecot-sql.conf need to be written to /etc/dovecot/* and overwrite /etc/dovecot/dovecot.conf in the process.
