What SIMS does is reverse the dotted-quad IP address and append the 
relevant DNSBL zone. So if a connection comes from 10.0.1.2 and SIMS 
is set to use the RBL and the ORBS 'inputs' zone, it will look for A 
records for:

2.1.0.10.blackholes.mail-abuse.org
2.1.0.10.inputs.orbs.org


If these come back with addresses in the SIMS blacklist (typically 
127.0.0.2, but other 127/8 addresses are also used by ORBS) then SIMS 
rejects the mail.

So, to look up a hostname, you first need to get its IP address, then 
build the blacklist name as abiove, and look that up.
