Hello,
Appended below is a quickie patch to the dnsbl plugin that allows you to
specify what nameservers should be used when doing DNSBL lookups.
This is very useful to me; hopefully some other people might have a use
for it.
In our office we have a server set aside to handle all DNSBL lookups -- we
mirror as many of the lists as we can locally on that machine for fastest
lookup times. Even for lists we don't mirror, by concentrating lookups
from our 800+ servers in this one place, we get a much greater benefit from
query caching.
Anyway, I'm currently looking for places we might use qpsmtpd in place of
qmail, and was pleased at how quickly I was able to get the plugin to do
what I needed. :)
