I can not find any place in the app where it allows me to define the  
hosts I want to lookup. The hosts a home users looks up over the hosts  
AASP or any other MTA / proxy will be entirely different.

The below tests I just ran now, on my MTA, not saying at all your  
results are not better, but based on the posts on reddit about just  
the the other day, we call come to agreement, good for home use, bad  
for server user with google any-cast IP space being the closest for  
server use. You could be in open DNS geographic, heaven, for me, I an  
not get behind a company that has known bugs in their resolver and  
does nothing to fix them.

First, these are all NON cachced results, since spam comes in waves, I  
am after the cachced results in this case.

For is a quick file of misc zones:
$cat zones
a.b.c.foo.example.com
abc.amazon.com
amazon.com
assp.sourceforge.net
bl.spamcop.net
google.com

Here is my command
for i in `cat zones`; do echo $i; dig $i @8.8.8.8 +norec | grep 'Query  
time'; echo "--"; done

I change the @NS to 8.8.8.8 to mine, to oprnDNS, to 4.2.2.2

For each line listed in zones, run a dig on it, using ip's for google,  
openDNS, and myself.  These are all run twice, with +norec

The good old 4.2.2.2. that has been around a long time before google  
or openDNS, these were not cached, amazing....

a.b.c.foo.example.com
;; Query time:          6 msec
--
abc.amazon.com
;; Query time:          6 msec
--
amazon.com

--
google.com
;; Query time:          6 msec
--
bing.com
;; Query time:          6 msec
--

Just too see how crappy comcast is, though I would give them a shot:
a.b.c.foo.example.com
;; Query time:          83 msec
--
abc.amazon.com
;; Query time:          83 msec
--
amazon.com
;; Query time:          82 msec
--
assp.sourceforge.net
;; Query time:          83 msec
--
bl.spamcop.net
;; Query time:          83 msec
--
google.com
;; Query time:          83 msec
--
bing.com
;; Query time:          83 msec
--

I ran them multiple times, these are good averages... For me, the way  
I have my DNS setup, and how I have local WL and BL zones, rbldnsd  
zones, etc, and how much faster my local lookups are, and how much  
more accurate they are to me at at the time, for now, I am staying  
with my sub 8 second results, or, moving back to 4.2.2.2

Thanks for the input.
