The mupdate server keeps track of which backend stores each mailbox.  You 
can have multiple backend and frontend servers, but only one mupdate 
server.  The frontend servers query the mupdate server to locate 
mailboxes, and the backend servers update the mupdate server when a 
mailbox is added or deleted.
