I'm having trouble with a client's DNS and mail where occasionaly the DNS seems
to cut out momentarily. If I run:
[ruben at mail ruben]$ dig rm-cpa.com mx
; <<>> DiG 8.2 <<>> rm-cpa.com mx
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
;; flags: qr aa rd ra ad; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2
;; QUERY SECTION:

There is only one authority.
If I look at other setups which I trust like wa3yre.wynn.com I get:
; <<>> DiG 8.2 <<>> wa3yre.wynn.com mx
;; res options: init recurs defnam dnsrch
;; got answer:

That is three authoritative servers. Are the other Authoritative servers
the secondaries registered with the NIC for a domain name? This is a DSL
connection which seems to have momtary outages. Can I use anyone as a authoritative
DNS and just make a record?
