can't spot anything obvious wrong. Just spotted that you are storing mails
in users home root along with all other files such as index files.

Maybe you should store the mailbox contents into Maildir:~/Maildir under the
users home and index to ~/index/

Someone who have mailbox in different directory than indexes, can confirm
if doveadm can recreate index (after deleting dovecot.index* files) or
these files can be created only by connecting with IMAP client?
