mailbox quota handling for client fails
short description
with some clients which have enough (or unlimited) quota for mailboxes, cannot create any more mailbox. I got this message :
The max space for mailboxes is reached. The max. available space in MB is: 0
correct behaviour
let me create the mailbox as client when therre is enough quota remaining
