For IMAP to be truely HA, you will need shared storage of some sort.
You can "emulate" a SAN with something like DRBD if budget doesn't
allow a
real SAN (that is what I do).
I can vouch for DRBD too. It works quite well.

Anyone used FileReplicationPro? I'm more interested in low
bandwidth, 'cheaper', replication.
I have never used FileReplicationPro but looking at what it offers it reminds me of GlusterFS. I use GlusterFS for all www data of the domains I host. I don't use jet GlusterFS for IMAP/POP storage for all domains I host. Only a small subset of the domains I host have GlusterFS for IMAP/POP but so far it works without issues and I will soon or later migrate the other domains to be on GlusterFS as well.
The setup of GlusterFS is ultra easy (compared to other clustering FS solution I have seen) and it offers some very nice functions.
In the past I have burned my fingers with older GlusterFS releases when I have tried to use it as storage for IMAP/POP but the later 2.0.x releases of GlusterFS are more stable.
