I have a new member trying to register for the site. He can load the register.php page but not POST the page. For each registration attempt shows 'Protector rejects your post, because your IP is registered in RBL' I have removed all records checked with his IP address. Although the IP address is not listed in the table he still cannot register. He can browse the site but not post forms. Is there any way to determine which rule is causing his registration problem? Does the reliable IP addresses work like 'white listed' addresses?

Thanks for assistance.
