Many Thanks, outstanding work.
Updated manually each of my multi-server setup. Old style

Few issues with permissions and with my 2 SSL certificates. Nothing major.
Also upgraded my roundcube installation to 0.8.5. Was using the ubuntu repository 0.7.1 or 0.7.2. So had to do a manual hack of everything to upgrade. Remember reading some user bugs of roundcube and ISPConfig3, so far no issues detected
