limit

I've bought a domain, say mydomain.com. I'd like to set up google apps to work with it. As such, I'd like to create subdomains like mail.mydomain.com, docs.mydomain.com, etc. To integrate it with google, I must add to all of them CNAME records to ghs.google.com. However my domain registrar says that they can create only one CNAME in my domain, for which they chose mail.mydomain.com. The rest of them, they say, I must create as A type records.

Are they being lazy, or is there some limitation here that I'm not aware of?

This is bit of a theological question, but nonetheless...

The very same server has multiple interfaces on different subnets. Let's… >>> More
