Well, it seems pretty straightforward to me, a humble end user... here
is a query:
gandalf:~$ dig @ns0.me1.aone.net.au movielink.net.au
; <<>> DiG 8.2 <<>> @ns0.me1.aone.net.au movielink.net.au
; Bad server: ns0.me1.aone.net.au -- using default server and timer opts
; (2 servers found)
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 6
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; QUERY SECTION:
;; movielink.net.au, type = A, class = IN
;; Total query time: 38 msec
;; FROM: gandalf to SERVER: default -- 127.0.0.1
;; WHEN: Fri Apr 14 21:44:05 2000
;; MSG SIZE sent: 34 rcvd: 34
IMHO, returning SERVFAIL is a Bad Thing(TM). I do not by any means
consider myself either a DNS or SMTP wizard, but I would think that when
the SMTP server tries to resolve movielink.net.au, it should get some
sort of answer, not either of SERVFAIL or NXDOMAIN*. For example, Mr.
Bernstein's domain:
gandalf:~$ dig cr.yp.to
; <<>> DiG 8.2 <<>> cr.yp.to
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
;; QUERY SECTION:
;; cr.yp.to, type = A, class = IN
;; ANSWER SECTION:
cr.yp.to. 0S IN A 131.193.178.181
;; Total query time: 922 msec
;; FROM: gandalf to SERVER: default -- 127.0.0.1
;; WHEN: Fri Apr 14 21:49:56 2000
;; MSG SIZE sent: 26 rcvd: 42
So, it looks to me as if the domain name must resolve to an A record.
* I believe it was mentioned earlier in the list that perhaps if the DNS
answered authoritatively that there was no such animal as
movielink.net.au, the lookup would then fall back to the MX record's
name, mail.movielink.net.au. I cannot be sure if that is the case,
having always made sure that the domain name resolved to an A record.
