Dovecot feature script does not support centos, has some slight problems
When executing the dovecot script it may fail due to severall problems:
- uses yum in interactive mode which breaks automation on centos
- has some hardcoded ipv6 config which may breaks on non ipv6 systems like openstack
- dovecot/postfix config is duplicate (at initial-config.sh and the dovecot.sh script)
- hardcoded, unquestioned reconfiguration of the OX users when executed after the initial ox installation
