All of the blacklists used are IPv4 only. Can we stop dns_verify.so from requesting IPv6 (AAAA) records from DNS?
Example IPv6 queries hitting DNS hosts as a result of using dns_verify.so:
14-Jul-2016 19:02:13.850 queries: info: client 17.xxx.xx.51#29326: view default: query: 17.xxx.xxx.66.spambl.oracle.com IN AAAA + (17.xxx.xx.9)
14-Jul-2016 19:02:13.851 queries: info: client 17.xxx.xx.66#31420: view default: query: 124.xxx.xxx.204.spambl.oracle.com IN AAAA + (17.xxx.xx.9)
If we could reduce the DNS traffic by half that would be helpful, especially since that half will never ever succeed or be useful.
