Wrong type of query
$ dig +short mirrors.updates.spamassassin.org txt
"http://spamassassin.apache.org/updates/MIRRORED.BY"

spamassassin.apache.org has 2 ip addresses on 2 continents and
MIRRORED.BY can be cached by sa-update for 7 days. Having the file on
the actual mirrors would place unnecessary restrictions on how these
third-party http servers are configured.
There does however appear to be a minor problem here.
The http headers for MIRRORED.BY have a last-modified date,
but no explicit expiry information. The relevant RFC allows an http
proxy to cache the file for up to 365 days before a get-if-modified
request is needed. Most caches set a lower limit, and if curl is used,
it requests the proxy go to the origin server, but there is scope for
getting a very stale file.

mirrors.updates.spamassassin.org. 3600 IN TXT
"http://spamassassin.apache.org/updates/MIRRORED.BY
well, that's somehow crazy, normally one makes dns round-robin for a
hostname and then load that file from one of the mirrors because all the
mirrors don't help much when "spamassassin.apache.org" is down

Yu Quian, please, use copy&paste, not screenshots of textual output!
does this problem persist? which version of Net::DNS do you have?

Please, get rid of nslookup. One of its main problems is that it produces
invalid output in many cases, this is one of them.
"dig any mirrors.updates.spamassassin.org. @b.auth-ns.sonic.net."
produces OK output.
