run a local caching server, then you can get results straight from
authoritative servers and also reduce number of requests/speed up rbl
lookups.

one of workarounds is using local caching service like dnsmasq that can
filter out those (bogus-nxdomain directive)

I am setup, at the moment, to provide a caching DNS that goes off to
the root name servers IFF the primary servers are not present. If they
start providing the search service I simply yank the ISP's name server
from the DNS cache configuration. I figure I could also substitute
any other nameserver I can LEGALLY attach to in place of going off to
the root servers. But they make a really good backup.

Another solution is to use a nameservice that doesn't change
DNSBL results. One such service is:
http://www.opendns.com/
See:

and:

It seems to me the best solution is to run your own local caching DNS
server. If there are a reasonable amount of duplicate queries then this
could help performance substantially.
Of course, I've never been a fan of using a DNS server that I don't
control ever since providers realized they can make money by telling you
what they think you were looking for.
