Unfortunately it wont work and according to the devs, it should never 
work that way, because this way you could potentially create 
inconsistencies on the master server.

Fortunately there is a patch that add this capacity to ctl_mboxlist, you 
can find it here:
http://asg.web.cmu.edu/archive/message.php?mailbox=archive.cyrus-devel&searchterm=ctl_mboxlist&msg=905

But as I mentioned above, you can easily end up with an inconsistent 
mailbox list on your master server.

It's because your master mailboxes.db is corrupted. The master server 
will behave crazy.
