I just finished setting up a similar setup.  I used drbd 
<http://www.drbd.org/> and heartbeat over the drbd interface to do a 
failover of the primary fails.  I also have a separate front end box 
that spools all the incoming mail to the amavisd-new content filter 
which sends it to the backend server to be stored into cyrus.

Murder doesn't provide failover, it only splits up the spool across 
multiple servers.  I believe that support for a load balance/fail over 
type setup is being added into the CVS cyrus.
