That's not "Consumer Friendly", that's just WRONG! Glad you found it. Dan <snip> The caching DNS servers we not accessable to the email serrves so they had no DNS. I decided to point the /etc/resolv.conf file to opendns.org's DNS servers and it does some tricky things and what it returned caching for spamhaus isn't what I think spamhaus was sending. They were making consumer friendly responses to point not founds to their search engine.
It was a decision during a crisis and it turned out to have inintended consequences. </snip>
