You don't 'ping' an RBL - they have to have an A record for the zone
name at all (and most don't). The only requirement is NS records:
[root at mail ~]# host -t NS zen.spamhaus.org
zen.spamhaus.org name server l.ns.spamhaus.org.
zen.spamhaus.org name server c.ns.spamhaus.org.
... snip ...
The standard way to test an RBL is via a test point, which is usually
[root at mail ~]# host 126.96.36.199.zen.spamhaus.org
188.8.131.52.zen.spamhaus.org has address 127.0.0.2
184.108.40.206.zen.spamhaus.org has address 127.0.0.10
220.127.116.11.zen.spamhaus.org has address 127.0.0.4
Spamhaus will return a DNS status of REFUSED if you are blocked by them
and you will not get any test points returned.
Hope this helps.
