I decided to create a small mail server. I use: postfix, dovecot, postfixadmin, the database of accounts in mysql (tabels create by postfixadmin). Everything onCentOS6. Unfortunately the server does not work. Logs: Permission denied! But, Permissions to the directory / mail where I store the correspondences: Dovecot config: /etc/dovecot-mysql.conf file: command user_query is correct? Tables in mysql databases: Can You help me ?
