be careful with openDNS and other providers as you want to make sure you have them set to not do their 'magic' stuff (I believe openDNS has a setting you can configure so they don't do their automatic redirection stuff if you want to use it with a mailserver).

If you're doing any volume of mail, it is useful to run a caching resolver locally on your mail machine.
