bradleyit.com CNAME = not good

I learned today that one should NOT set up a CNAME record for your domain, only subdomains. If you do, you will break your MX records and emails will be lost in the ether.

For example, this would be bad:
bradleyit.com  CNAME  anything.com
However, this would be ... ok:
sub.bradleyit.com CNAME anything.com
So if I haven't replied to an email you sent to my new address, I'm sorry, I wasn't ignoring you. I had just crippled myself.

I have since corrected this problem so now I should be receiving your email without delay just as soon as the DNS propagates. Also, if you have bookmarks pointed at "bradleyit.com" in your browser, you'll need to update them to "www.bradleyit.com".
