Not sure if this is the result of a recent upgrade but as of 4 days ago, mail has stopped flowing. We have postfix configured to send mail only, which has been working flawlessly. No modifications to config, but mail is in queue and cannot be delivered. Error in log is "warning: mysql:/etc/postfix/mysql-virtual_outgoing_bcc.cf is unavailable. open /etc/postfix/mysql-virtual_outgoing_bcc.cf: Permission denied" The permissions on the file appear to be 600 for rootostfix. Any recommendations/suggestions?
