     I missed this in my latest response:

>1) I am able to use custom DNS-Servers for both my client and others that use my exit point, without the warning messages.

     Those warning messages are caused by client-side code in tor in response
to requests made to its SOCKS port; they are not issued as a result of your
relay providing exit services.

>2) My, the operators, custom DNS-Servers can speedup _and_ aid in anonymity by blocking/re-directing certain domain names to other IP's.

     Providing such a page as a substitute for a response from the proper
destination is in itself justification for immediate classification of your
exit relay as a bad exit.  *Any* alteration/substitution of data qualifies the
culpable exit relay for a BadExit flag.
