So bottom line is to use a filesystem such as XFS, distribute and dedicate mailboxes to a number of backend imap servers optimally with direct access to the storage and do imap proxying and loadbalancing in front of those servers.
Then you should also balance incoming mail and local deliveries and this part is tricky. Also, there should be a hearthbeat/pacemaker for filesystem/IP/services failover.
Every choice is a compromise. So you should balance a lot of factors: complexity, administrative overhead, FS limits, performance, stability etc.
