I'm not a Linux user, but I often see messages like this where
various enhanced security packages cause problems, have you
ruled these out?

Either that or deliver is being run as user with insufficient
rights. You shouldn't have to chmod the mail store, the
delivery program assumes the appropriate credentials. At least
that is how I understand it.

Hope this helps,
