I am currently trialling the VM appliance ZCA and had a few questions:

1. After installing am I able to increase the disk space available? Initially it seems to be a 18GB appliance with 11GB of mail storage. Is there an option (or future development) to be able to increase the storage space or to use some other external storage for the mailstore?

2. What about Quota Management for users - total storage, max email/attachment size both send and receive, groups of users, etc...

I can't seem to find any tab or settings page for this sort of information.

3. What about reporting? eg: Displaying what users usage is, Mail Queues.
