Actually, that *is* your most urgent problem. Without these Postfix cannot work, regardless of the rest of the configuration The $queue_directory must have various requisite subdirectories with correct ownership. If the queue_directory has POSIX ACLs or some other barrier to creation of the required sub-directories, then Postfix is unusable. -- Viktor.
