Try removing the dovecot index files, eg. if the users mail dir is in
/home/user/mail/[hidden email], you would want to remove:
Once they are removed, tail the dovecot log files (and perhaps turn on
debug logging) and then log in to the account again, usually if it fails
to recreate the index files (permissions?) it will write out a log
message saying that.
There is index files per sub folder as well, so if you just want to
clean them all up you could use something like this to view the list of
commands that would be ran:
