I think there's an issue with sorting mailboxes by quota, on multi-page mailbox lists While logged as admin, I go to Statistics->Mailbox Quota, I see some pages of mailboxes with their currently used quota in columns. If I sort the mailboxes by usage, only the current page gets sorted and not all mailboxes present on the server. This makes it hard to see who is using most of the space (which I in turn use to check for abandoned accounts). When going to the mailbox traffic page instead, sorting works as supposed. ispcomm.
