It's going to depend on your network path to OpenDNS also.  I personally
have never found it faster to go off network (OpenDNS) then do lookups
myself.  Especially on a mail server since alot of your SPAM comes in
batches the lookups to the same domain are going to much significanly
faster in that respect.

I've tried OpenDNS quite a few times and although its good and it is fast
it has never beat going local in my test enough to increase my traffic
going out/in from the internet.
