Dave,

Since you're referring to a domain, I think you misunderstand what this
CASA DNSBL lists.  It only lists IP addresses.  MXToolbox looks up the
IP address of your MX and reports any DNSBL hits it finds.

These are normal return codes, although most people use 127.0.0.X for
listed entries.  For instance, the IP address 12.75.2.1 is currently
listed in the Spamhaus PBL list:

 $ dig 1.2.75.12.pbl.spamhaus.org +short 
 127.0.0.11

A brief explanation in English is here:

Which of those lists contains the IP address you're talking about?  MXToolbox
should say.
