Within the /var/log/mail.warn i found the following warnings: warning: redirecting the request to postfix-owned data_directory /var/lib/postfix warning: request to update table btree:/var/spool/postfix/smtp_scache in non-postfix directory /var/spool/postfix What do these warnings mean and how can this be solved? (This is a Debian Lenny server with ISPConfig2)
I've never seen such warnings before... Did you modify your main.cf? Do you use Maildir or mbox? What's the output of Code: df -h ?
