Re: Holy undergarments
OpenDNS is not really a good thing to use for a server that needs to know if a hostname is valid or not. OpenDNS will reply with a fake address that points to them for invalid hostnames. This is cool if you want some special notice web page that the hostname doesn't exist page etc... but for a mail server, not knowing the hostname is not valid is a waste of system resources... NXDOMAIN is the better response.
Google DNS is fast, though using resolver.qwest.net is faster at the moment.
