The server is located in a well-known computing centre in Nuremberg,
Germany. I assume they know how to handle DNS services.
Are you sure it's 127.0.0.1? This is at the top of all Spamhaus zones:
:127.0.0.2:http://www.spamhaus.org/SBL/
the goal aws to test an _unlisted_ IP, to detect NXDOMAIN "hijacking"
(aka "ISP error page") and 127.0.0.1 is a good example.

you can of course use any name that is known to return NXDOMAIN.
Which does yield correct results:
smtpgate# host 2.0.0.127.zen.spamhaus.org
2.0.0.127.zen.spamhaus.org has address 127.0.0.10
2.0.0.127.zen.spamhaus.org has address 127.0.0.4
2.0.0.127.zen.spamhaus.org has address 127.0.0.2
