Yes, with director it should be something like that:

MTA --(lmtp)--\               /--(lmtp)--> backend1 --\
                 -- director --                         -- NFS
MTA --(lmtp)--/               \--(lmtp)--> backend2 --/


IMAP-User --> frontend1 --\              /--(imap)--> backend1 --\
                            -- director --                         -- NFS
IMAP-User --> frontend2 --/              \--(imap)--> backend2 --/


So what happens if user1 at example.tld receives a mail?

- The director decides to connect to backend1 which in turn stores
the mail on the NFS share and the index file locally?

- Then, user1 at example.tld connects to one of the frontends. Does the 
director know that, earlier, this user received a mail and proxies him
to backend1 too?
