Then nslookup is telling you something it has no way of knowing. Lookups of
enterprises.net time out; they don't return NXDOMAIN. The timeout is a
temporary error, and qmail has no way of knowing whether this condition will
last. According to the root servers, enterprises.net is supposed to exist, but
none of its listed name servers is answering questions about it. This is not
the same as a root server saying "there's no such domain," which would be a
permanent error and would cause qmail to bounce the message immediately.
