-
-This was added in 5ce3e76fbf89e942e8c54ef3e3389facf0d9067a but
-it trips over too many buggy clients that leave an interface configured

-Subject: [PATCH] Try other servers if first returns REFUSED when
- --strict-order active.
-
-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.
