[Pdns-users] pdns-recursor lua script - redirect query

[Frank @ kiwazo.be]

Hi Grzegorz,

If you're a paying Spamhaus customer, then using their RPZ service might be a way easier solution than redirecting the queries? 

Please see the PowerDNS specific docs at https://docs.spamhaus.com/dns-firewall/docs/source/configuration/power_dns_config.html

Should you have any questions, let me know. 

Cheers,

Frank
