<p class=MsoNormal>Hi Simon,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I would like to request the ability of dnsmasq to lookup dns
names on blacklist servers. If the dns name is blacklisted then return a
specified configurable address, like 127.0.0.1, or a not found error instead
of the true address and add it to a blacklist cache. I see it working something
like this.<o:p></o:p></p>
