 |

Yes, DNS, not DNF. 
Hey, I'm looking for someone that knows how to configure DNS. Specifically MX records. I have a cloud server at Rackspace and I thought I had everything setup correctly but when I ran some diagnostics, it's telling me I shouldn't have a CNAME in my MX record.
These are my settings at GoDaddy: (bogus ip address and domain name)
A @ 7.14.27.10
CNAME mail @
CNAME test @
CNAME www @
MX @ mail.geopierce.com
I have my reverse DNS setup at Rackspace to point mail.geopierce.com back at my ip address.
Is it as simple as removing the CNAME for mail?

Well it's been a while and I don't understand GoDaddy's weird format but I'll give it a try. I assume @ is supposed to be geopierce.com. Since everything points to the same IP address anyway, this will probably work, but isn't a good idea. If you remove the cname for mail, then mail.geopierce.com won't be defined and mail will bounce, unless you have a wildcard entry set up. I think you want something like:
A @ 7.14.27.10
A mail 7.14.27.10
CNAME test @
CNAME www @
MX @ mail.geopierce.com
either that or just get rid of the MX record. |

Thanks Paul! Removing the CNAME and adding the A record got rid of the warning in the diagnostics. I'm a developer, not an administrator.

| Should your WWW and the TEST hosts be A records? None of my DNS entries use CNAME records anywhere and based on what I read, sounds appropriate, at least in terms of how I use it. |

CNAMES are for aliases and make it easier to update your DNS if your ip address changes. I suppose you could use all A records if you only have a few subdomains.

Right, but I've been able to update my A records just as easily. |
