Version controlled (git) Maildir generated by Dovecot

IIRC the plain files from cur/ and new/ should suffice.

You can try it: create a new IMAP folder, then close your mail app.
Copy some mail files from another cur/ to this imap folder's cur/ directory.
Reopen your mail app and see if new mails are fetched.
