Well, there are other DNS servers more specifically made for hosting 
RBLDNS zones, but the basic format of an RBL zone is the reversed 
addresses of a dotted quad, tacked onto a zone, and looked up with A 
records.

thus, for a listing of my posting server, prime.gushi.org (72.9.101.130, 
to use a real world example)...in the fictional blacklist 
"bl.myrbl.com" you would be looking for an A record for 
130.101.9.72.bl.rbl.com.

The return codes of most RBLs are specific to THAT RBL.

For example, rfc-ignorant.org will return those listed here:

The ones for spamhaus:

http://www.spamhaus.org/faq/answers.lasso?section=Spamhaus%20XBL#136

And so on, et cetera

But the general assumption is ANY return is cause for blocking, unless 
your software is specifically looking for more specific codes.

Hope this helps,
