response-policy zones from spamhaus.org

[MAYER Hans]

Dear All, 

We are using response-policy zones as a service from spamhaus.org
This is used for web access as well as for SMTP ( incoming and outgoing ) 
Actually this worked fine over years. 
Now we have the situation if I dig www.airindia.in I get as result 

;; ADDITIONAL SECTION:
bad-nameservers.rpz.spamhaus.org. 60 IN SOA need.to.know.only. hostmaster.spamhaus.org. 1507403414 300 60 432000 60

This indicates that it is listed in the  bad-nameservers.rpz.spamhaus.org database from spamhaus.org which I have configured as a slave zone in my DNS server.
Our employees are travelling a lot and therefore it is not acceptable that the Indian Airline is not reachable. 

Such zones are defined as type slave. Therefore it’s not possible to update such a zone. 
I also tried to define these records in my own RPZ and hoping it has higher priorities. But it isn’t. 
Finally I tried a forward only zone for airindia.in to a server in my environment which does not use RPZ. But this doesn’t work too. 

Any ideas how I could shade or overwrite the content of RPZ ? 

I am using BIND 9.11.2


Kind regards 
Hans
