Since starting to use OpenDNS and using their servers as forwarders

I am assuming it is SpamAssassin causing this but I could be wrong.
Personally I wouldn't use OpenDNS on a server (except maybe for
squid). It's not a normal DNS server, it does things that are aimed at
browsers like spelling correction, and redirecting failures to it's
own
web servers. The latter presumably breaks the NO_DNS_FOR_FROM test,
and I wouldn't be surprised if other tests are affected too.
While this is generally true of most DNS services LIKE OpenDNS,
OpenDNS itself is pretty clueful. Unlike the people at uribl...
"onoes, we're getting 50 million hits a day from openDNS, let's block
them, annoy all their users, and not reduce our hits at all because
people will simply reconfigure to hit us directly instead of via
OpenDNS. But at least those 50 million hits will be over slower links,
and consume more of our resources. yeah, that's a GREAT idea."
Or am I wrong? I could be wrong.
