Hello, my CentOS 6.2 server sends the daily messages correct e.g. today at Feb 1 03:31:14 At the beginning of work hours (9:00 am local time): Feb 1 10:06:17 server postfix/sendmail[27125]: fatal: chdir /var/spool/postfix: Permission denied Solution: restorecon -R /var/spool/postfix/ Afterwards, postfix is OK again. My own cron jobs will be run latest 1 am What daily cron job destroys the selinux permissions? -- Viele Grüße Helmut Drodofsky Internet XS Service GmbH Heßbrühlstraße 15 70565 Stuttgart Geschäftsführung Dr.-Ing.
