Can you explain a bit more what you mean? (maybe with screenshots or logs)?
If you like to know how much a listed url/ip raises the spam-score of an e-mail:
* for the RBLs configured at the Mail Proxy level - if the ip is listed the mail is not accepted
* for the Spam Checker (SpamAssassin) you should see the score in the headers of a processed mail
I am unable to release sites that are being blocked by RBLS, even by entering domains in the WHITE list (In Mail Proxy settings, and in Who Object), they are being blocked in RBLs as reported in Trakin Center, so I wonder if RBL blocking rules priority is above WhiteLists.
