Hi, so on my domain computershine.co I deleted using linode DNS Management the mx record mail (mail.computershine.co) and added mx entries for google apps.

48 hours later and when I type in mail.computershine.co I am served up the default index.html from my document root.

This is not an issue at all because when I add a CNAME for mail.computershine.co that will no longer happen. I know this because I already set it up on another virtual host domain that I have.

I'm really just wondering what is going on with this here? Why do I not just get the default OpenDNS page I would get if I typed some other random non existent subdomain? I am only asking this question out of curiosity.

Thanks, Mike

PS I have a very basic install so far with just two virtual hosts.

Looks like your MX records are set up correctly, and you have no entry for mail.computershine.co. You might have had your Linode's address cached somewhere for mail.computershine.co, either on the nameserver you're using for lookups, or on your local machine.
