Hi,

we had nearly the same problem. We solved this by buying an external root-server (We use a Strato package) and install Kolab on this machine
For a faster backup its useful to have the imap dirs on an intranet machine. So we use a master slave setup. Master-Slave communicate via openvpn. imap dirs are on the slave. root-server is kolab master. master is smarthost of the slave.
