Quarantined mails are not displayed at all

I found a new problem in admin panel.  As a global admin i am allocating 200GB as domain quota and max per user quota as 5GB.
But domain admin could change the user quota to unlimited, by setting the value to 0 (domain admin should not be able to change max mailbox set by the global admin but domain admin is able to change) and users are able to receive mails even after the domain quota of 200GB exceeded.  We are having 3 separate servers with  iRedamin-Pro license, but in all the 3 servers we are facing the same issue. Please some one help me resolve the issue.

Thanks in advance
