can we have a total mail quota per package.
it's typically fine for packages where mailboxes are all the same defined size, the total email disk quota is number of mailboxes x defined mailbox quota.
eg, 5 mailboxes, fixed size of 5Gb per mailbox, total mail disk quota limit is 25Gb
but the dynamic mailbox quota needs a total limit..
at the moment, we can define the number of mailboxes, and the maximum size the customer can specify for an individual mailbox.
eg, if i want to allow a similar total email disk limit of 25Gb, but the customer to have 4 small mailboxes and 1 large mailbox, we can't do that. i could specify the dynamic mailbox limit as 25Gb, but there's nothing to stop each of those mailboxes going up to 25Gb, for a total disk quota of 125Gb.
dynamic mailbox quota's needs to have a limit for each individual mailbox and a total combined limit for all mailboxes
