Any advance on Feisty support on current releases of Zimbra? Our Zimbra installation is failing users regularly which looks bad for something badged as an "upgrade from MS Exchange 2003".
The fails are caused by no iSCSI support in Ubuntu Dapper, so the (large) mailstore volume is attached via the VM host rather than directly in the Zimbra VM. Anything that hammers that connection, such as migrating users, prevents access to Zimbra.
Ubuntu and Zimbra are both parts of the same corporate strategy, so moving to another OS/Linux distro is not really an option.
