Spamhaus RBLs

[Steven Andrews]

When they "firewall" you, I'd assume they block your address entirely and that you couldn't even ping their IP.  It appears he's trying to ping by the host name and is not getting an address at all; not that the ping is failing.

To me, this smells like a DNS lookup issue, not that they've blocked you.  I've tried it from a couple different networks, some it doesn't lookup, some it does.  I tested a control network that doesn't have any reason to be looking up anything at spamhaus and it fails; my Comcast using opendns resolves those hosts fine.  Pings to the IP address the host should go through fine.

Checking dnsstuff.com A record lookup, zen.spamhaus.org has NO A or CNAME records at this time, even according to their parent servers.

Please correct me if I'm interpreting this incorrectly.

It sounds like they firewalled you for "going over their limit".
