Occasionally, the ubiquity of the custom domain curse
Server Not Found

Error 404
surprises even me. In this case, as in many others, the domain is properly setup.

mydomain.com.            3600    IN      A       216.239.32.21

An an (abbreviated) HTTP trace gives intriguing details.

Even FeedBurner, it appears, is involved in the Google Apps quagmire.

Fortunately, there's a possibility to sort this. We may be able to use the FeedBurner MyBrand wizard to remove the domain mappings.
  1. Use the FeedBurner MyBrand wizard, and define "feeds.mydomain.com" in Step 1 of MyBrand.
  2. Add a new virtual host to your domain, defining the target URL, as specified in Step 2 of MyBrand.
    feeds.mydomain.com.      3600    IN      CNAME   1e0jtkx.feedproxy.ghs.google.com.
  3. Activate the MyBrand service.
  4. Deactivate the MyBrand service.
