No, you want to cluster your mailstore (IMAP, POP, ...). This is not
Postfix. Multiple Postfix MX hosts do not need to be clustered, the
SMTP design automatically load-balances multiple MX hosts.
In an HA environment, your front-end SMTP servers would not be where
you store your mail, rather the clustered IMAP servers would be behind
the MX hosts, which are not clustered.
Designing a clustered mail store is an interesting problem, but really
a Postfix issue.
