Email is being delivered even though sender's IP address was registered in DNSBL 'Spamhaus.org'.
Listing the IP address in PBL (Policy Black List) does not restrict the overall mail flow from the mentioned IP, but only that mail where SMTP Authentication is turned off.
If sender uses SMTP Authentication during the delivery, the message will be delivered fine.
Place unwanted IP into another black list.
