If a DNS server replies REFUSED for a given DNS query in strict order mode no failover to the next DNS server is triggered as the failover logic only covers non strict mode. As a result the client will be returned the REFUSED reply without first falling back to the secondary DNS server(s).
Make failover support work as well for strict mode config in case REFUSED is replied by deleting the strict order check and rely only on forwardall being equal to 0 which is the case in non strict mode when a single server has been contacted or when strict order mode has been configured.
