Maildir was designed to work over NFS but I don't think that anyone cared much about performance. Mail servers tend to either be small enough that performance is never a problem or big enough that NFS just isn't viable.
Dovecot and other IMAP servers should work together. Dovecot is designed to regenerate indexes when necessary. I don't think performance would suffer much given that a common use case is having a program other than Dovecot doing delivery.
