It seems this must be owned by postfix but it was owned by root.
So, can somebody check to see if this is there in a CentOS 6 Postfix install where Amavis is not installed? And if so, what are the default permissions?
maybe try rpm -qf /var/spool/postfix/private/auth to see if it belongs to an rpm. You could then rpm -V that package if it exists.
