The CNAME RRs do work:

The problem you experience is that Google sees the original request:
http://blogspot.teo-en-ming.com/

and respond:

*404.* That’s an error.

The requested URL |/| was not found on this server. That’s all we know.


You probably have to make a redirect from a web server that you own so
the request can be corrected to the appropriate address (header
information) to show Google.
