Upgraded to BIND 8.2.3: Cannot resolve external domains

[Per magne Knutsen]

I've recently upgraded BIND from 8.2.2 -> 8.2.3. Domains that are hosted on the server resolve ok. However, I cannot resolve any other domain hosted elsewhere.

Running dig with a local domain:

; <<>> DiG 8.3 <<>> positivt.net 
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 4
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 1, ADDITIONAL: 1
;; QUERY SECTION:
;;      positivt.net, type = A, class = IN

;; ANSWER SECTION:
positivt.net.           1D IN A         216.87.215.44

;; AUTHORITY SECTION:
positivt.net.           1D IN NS        ns1.nethut-cblt1.net.

;; ADDITIONAL SECTION:
ns1.nethut-cblt1.net.   1D IN A         64.65.32.34

;; Total query time: 9 msec
;; FROM: ns1.nethut-cblt1.net to SERVER: default -- 64.65.32.34
;; WHEN: Sat Feb 10 16:26:03 2001
;; MSG SIZE  sent: 30  rcvd: 93

Then, on a domain hosted elsewhere:

; <<>> DiG 8.3 <<>> telenor.no 
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 4
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0
;; QUERY SECTION:
;;      telenor.no, type = A, class = IN

;; Total query time: 8 msec
;; FROM: ns1.nethut-cblt1.net to SERVER: default -- 64.65.32.34
;; WHEN: Sat Feb 10 16:25:44 2001
;; MSG SIZE  sent: 28  rcvd: 28

BIND is, admittedly, a big mystery to me (though I find myself learning ever faster under the current pressure...). I'm not sure what information is required for debugging here. named is of course restarted, and the new version is running:

ndc> status
named 8.2.3-REL Tue Jan 30 16:56:25 PST 2001  admin at despair.cobalt.com:/home/redhat/BUILD/bind-8.2.3/src/bin/named

Logs are littered with sendmail error messages like these:

Feb  9 15:01:48 ns1 sendmail[5805]: PAA05805: ruleset=check_mail, arg1=<icnlist-bounce at mail.infowar.com>, relay=[198.252.45.164], reject=451
<icnlist-bounce at mail.infowar.com>... Sender domain must resolve
Feb  9 15:01:49 ns1 sendmail[5806]: PAA05806: ruleset=check_mail, arg1=<icnlist-bounce at mail.infowar.com>, relay=[198.252.45.164], reject=451
<icnlist-bounce at mail.infowar.com>... Sender domain must resolve

That is, no outbound mail escapes the server.

Does anyone have an idea of might be wrong? I haven't included any configuration files, as I'm not sure which ones are the relevant. In any case, all local domains resolve ok from anywhere. Its just resolving external domains from the box that persistently fails.

Advice is greatly appreciated!

Sincerely,
Per M
