* isBlacklistedDns is a generic function to provide extensibility

* pos_resp: An array containing responses that should be considered
* a positive match. If not provided, will assume that ANY
* successful DNS resolution against the DNSBL should be
* considered a positive match.
*
* For example:
* isBlacklistedDns('1.2.3.4', 'dnsbl.com')
* Returns true if 4.3.2.1.dnsbl.com returns any DNS resolution.
* isBlacklistedDns('1.2.3.4', 'dnsbl.com', 2)
* Returns true if 4.3.2.1.dnsbl.com contains '127.0.0.2' in its
* response.
* isBlacklistedDns('1.2.3.4', 'dnsbl.com', array(2, 3))
