Have you looked at a software called balance which would offer load
balancing capabilities ?
I would use something like Courier IMAP as it also has an IMAP Proxy
server which could come in handy for a wide range of things. I think that
you can create something like /mail and put maildirs there, then dump them
with a dump utility for example you could use xfsdump/xfsrestore if you
used the XFS to do things.

Use qmail with vpopmail and all the mail ends up (by default unless you
change it) in /home/vpopmail/domains/domainX/userX/Maildir .

and that's perfect. I don't think dovecot would do it that way.

I have postfix sending the mail to a /home/vmail/domains/<domain>/<user>
style arrangement. Dovecot handles this arrangement nicely as well.
Rsync should be able to handle it pretty easily via cron job, but it
would be nice if I can reliably take it to a lower level.
For receiving external mail, I can simply list both (or more) of the
mail servers with MX and let them sync each other. For joe internal
user sending mail and accessing via IMAP, I would do an LVS or
round-robin DNS style thing to get them to one of the servers. While I
may have a brief interruption in the event of a server failure, thats
acceptable at this point.

I would be taking this up with a dovecot list since they are certain to
give you much better real world experience with these ideas.
