<div>These lines did not happen with Dovecot 2.3.2.1. <strong>doveconf -n</strong> output below. I have also tested to create an emty file with <strong>userid entrega</strong> in <strong>/etc/dovecot/virtual/</strong> and works, so it does not seem a problem with permissions. Any idea about this problem?</div>
