I think /indices_dovecot/indices/11/21/espi/mailboxes/CURSOS/ACCION SOCIAL/dbox-Mails exists, but this one doesn't? So it's a desync between what exists and what doesn't. A fix would be to either delete the folder from the indices_dovecot or mkdir this missing directory back. I guess it would be nice if Dovecot would mkdir it back automatically. Although I don't know where the stat() errors are coming from exactly - I tried a few tests and I could get a different error by trying to APPEND to the folder, but couldn't figure out how to trigger a stat() error.
