Took me quite a while, to get everything right … – Google Apps (I call them GApps for short) would like to take over an entire domain, but I cheated them to just take over a subdomain with a couple of sub-subdomains. Learned quite a few things that way. Funny: How can a subdomain of mine “host” Google Apps? You simply point its CNAME DNS entry to the right Google host FQDN and here we go! That host looks up entries in a table, that you set up before, and it fills those poor sub-subdomains of mine with a nice life. It’s amazing! I’m not sure, whether the other potential domain users do enjoy Google Apps, but at least I showed them a possible way to go.
