It should be enabled by default, but the server uses an internal polling 
method by default (--with-idle=poll).  You can increase the frequency of

seconds down to 1 second.  If you want instantaneous notifications of 
changes without needlessly banging on the server with a small polling 
interval, then you should compile Cyrus with support for idled
