The configuration of the mupdate servers in the Cyrus Murder.  The
"standard" config is one in which there are discreet frontend (proxy) and
backend servers.  The "unified" config is one in which a server can be both
a frontend and backend.  The "replicated" config is one in which multiple
backend servers all share the same mailspool, but each have their own
"replicated" copy of mailboxes.db.
