Net::DNS problem?

[Rolf Kraeuchi <ro...@id.unibe.ch>]

Hi!

I just upgraded one of our Gateway (scan)servers from SA 2.61 to 3.04
(System is SuSE Linux Enterprise9/i386, SA invoked by amavisd-new 2.3.1).

Can anybody explain me the following message:

----------
scanhub02:~ # spamassassin --lint
;; remote addr struc: 020000357f0000010000000000000000
----------

Goggle did not really help, besides that I suspect this message is 
generated by the Net::DNS module (installed Net-DNS-0.50).

Now if I do *not* set 'dns_available yes' in local.cf:

---------
spamassassin -D --lint
[...]
debug: is Net::DNS::Resolver available? yes
debug: Net::DNS version: 0.50
debug: trying (3) comcast.net...
debug: looking up NS for 'comcast.net'
debug: NS lookup of comcast.net failed horribly => Perhaps your 
resolv.conf isn't pointing at a valid server?
debug: All NS queries failed => DNS unavailable (set dns_available to 
override)
debug: is DNS available? 0
[...]
---------

Of course resolv.conf points to a valid nameserver...

Any help appreciated.

regards,
