synchronization/backup mx

[Philippe Trolliet]

hi,
i´m looking for a strategy to synchronize the primary mailserver to a
backup/fallback server. i´ve read an article about backup strategy in the
cyrus wiki. but is there any other way to do this? e.g. with an internal
component of cyrus?
scenario:
a mail is stored in inbox on primary server.
the server stores a backup of the mail and config over a second network
interface on the backup/fallback mx.
is this possible or has this to be done manually with rsync/lvm snapshot?
can i realize this in some way with murder?

there is some other thing i want to know. is the backup mx (configured in
dns) automtically used if my primary mailserver goes down because of
hardware failure or anything else?

regards
philippe
