I've had to retrench our nameserver at work from 8.2.1 to 8.1.2
because of this problem.

For one particular domain, I'm getting "localhost" returned
in entirely incorrect circumstances by bind 8.2.1 installations.

Here are two real samples, the first from a machine running
bind 8.1.2:

; <<>> DiG 8.1 <<>> mx mossgas.co.za 
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 3, ADDITIONAL: 2
;; QUERY SECTION:
;;      mossgas.co.za, type = MX, class = IN

;; ANSWER SECTION:
mossgas.co.za.          3h23m2s IN MX   100 mail.mossgas.co.za.
mossgas.co.za.          3h23m2s IN MX   200 igubu.saix.net.

;; AUTHORITY SECTION:
mossgas.co.za.          3h22m18s IN NS  mossnet.mossgas.co.za.
mossgas.co.za.          3h22m18s IN NS  igubu.saix.net.
mossgas.co.za.          3h22m18s IN NS  sangoma.saix.net.

;; ADDITIONAL SECTION:
igubu.saix.net.         10h5m39s IN A   196.25.1.1
mossnet.mossgas.co.za.  3h22m18s IN A   196.25.60.10

On a machine running 8.2.1, this is what's returned:

; <<>> DiG 8.1 <<>> mx mossgas.co.za 
;; res options: init recurs defnam dnsrch
;; got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 1, ADDITIONAL: 2
;; QUERY SECTION:
;;      mossgas.co.za, type = MX, class = IN

;; ANSWER SECTION:
mossgas.co.za.          1D IN MX        100 mail.mossgas.co.za.
mossgas.co.za.          1D IN MX        200 mail.cape.intekom.co.za.

;; AUTHORITY SECTION:
mossgas.co.za.          1D IN NS        localhost.

;; ADDITIONAL SECTION:
mail.mossgas.co.za.     1D IN A         196.25.60.2
localhost.              3d4h20m54s IN A  127.0.0.1

Needless to say, returning "localhost" as an NS record
slows down mail delivery to them substantially. :)

I was having this problem with the 8.2.1 installation at
work, and retrenched to 8.1.2, which cleaned up things
completely. No configuration files were changed.

This is the only domain I know of that exhibits this
problem.  I'm totally stumped.  Is this an 8.2.1 bug,
or what?
