Good day David,
 
Thanks for the inquiry. Can you please reiterate the question and provide us an example of the scenario ? Do you have more than one RBL listed with different weights or do you have a RBL, such as DKIM that has Pass, fail, none weights ?  Please provide us an example of the log files where the spam checks are listed for us to determine the outcome.
 
Thanks.

The SORBS RBL (dnsbl.sorbs.net) can return multiple records if an IP is on multiple list like if the IP was on socks & http then it would return both 127.0.0.2 and 127.0.0.3. If I wanted to weight on both socks & http could I add an RBL with weight=10 and multiple Required Lookup Values like "127.0.0.2,127.0.0.3" and have the rule add the weight twice if it was on both lists or would I need to add a seperate RBL with each Lookup Value?

Quick answer is no.  Any single RBL test failure will only add the weight listed for that test even if it failed multiple levels of that test.  So yes, you would have to add additional tests if you want the weight to compound.  An URIBL will add the specified weight for every "hit" within the message.
