Yes indeed im running tor as both relay and client.
When i set my client to not resolve DNS queries using the tor network i get the warning messages.
(Which ofcourse are as expected)

My reason(s) for this scenario is so that:
1) I am able to use custom DNS-Servers for both my client and others that use my exit point, without the warning messages.
2) My, the operators, custom DNS-Servers can speedup _and_ aid in anonymity by blocking/re-directing certain domain names to other IP's.
Which will, in the case of OpenDNS, return a small HTML with a message telling its blocked.

Preventing the access to specific domains will, IMHO, improve anonymity for both the relay operator and the client using it as exit point.
I came-up with this scenario because i wanted to speedup the user experience _and_ kill the webs tracking behaviors as much as i can.

So i admit i understand that for my scenario to work without the warning messages tor needs an extra config option to allow IP-only requests from custom listed IP's in its torrc file.
(fe. localhost/ for the local client)

I understand that one can use Privoxy for even more advanced filtering, but a simple DNS-based filtering system is more than enough for most of the web-tracking systems IMHO.
Besides this approach will even enable tor to utilize bind+rbl :)
It's just IMHO the next step towards _more_ anonymity...

Oh and about the message and me not needing to look at them:
They are logged to stdout and presented in the log-window of vidalia.
The rest of the messages are still important enough to be seen by the operator.
