Hello,Today while looking at a different issue (one user couldn't retrieve mail; DNS issue) I set 'mail_debug=yes' then ran `dovecot reload` on our mail server. After running the reload, dovecot started complaning about permission issues with the dict file, and preceded to try to kill it's self. The self reload didn't seem to work, and since this is a production system, I was forced to restart the dovecot service. After the restart of the service, everything seemed to go back to normal. Dovecot is currently working as expected, no other permission errors in the logs.
Dovecot Version: 2.0.9 (3582271a897e) running on Fedora 14 running with a mySQL setup including dict tables (quota, expire). The virtual user's mail has a local user and group id of 1000.
