You're doing something very similar to what I've just done, though I'm using postfix. You will need to use drbd (www.drbd.org) for the server mirroring along with drbdlinks (http://www.tummy.com/Community/software/drbdlinks/) to sort out the transfer of filesystem from one machine to another. I advise you use an R1 configuration, as it's much simpler and you are in a basic 2-node failover scenario, rather than clustered services. You can see my ha.cf and haresources in an above post (though take it with a pinch of salt as it's part of an ongoing query). As an aside, I would recommend upgrading your MailScanner, as that is rather an old version and there have been a number of important bugfixes since then.
