Probably not the best place to put this, but it's still a bug and still present in the latest version.
The main email quaratine window doesnt re-size properly (if at all!). The management of the quarantine is poor - i.e. there's no filtering taking place (/user/subject/sender etc).
I think this whole area needs a good re-think as it's poor admins that will have to administer the quarantine area's. This is now competing against some pretty well qualified competition, but failing on the UI and management. Technically it's fine - just needs some time spending on the front end.
