Hello, I have a situation where PowerDNS Authoritative server answers queries differently from how BIND does it, when it is not authoritative for a zone.
PowerDNS (3.2): ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 59699 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; WARNING: recursion requested but not available BIND (9.7.3): ;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 16419 ;; flags: qr rd; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 ;; WARNING: recursion requested but not available The problem is that resolvers seem to treat this as a final answer, and won't proceed to the next server. Microsoft DNS (6.1): ;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 42689 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 BIND (9.8.4): ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 57604 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1 This creates a lot of problems where for example zone transfers fail, and for example customer mail bounces because the sending mail server believes there is no MX record. Any clues on how to solve this? Thanks, //Fredrik
