I am trying to implement Google Apps for a new domain of mine, and although Google says it can take up to 48 hours, it is normally much quicker than that, and other DNS changes, such as creating the domain alias, normally take less than 1 hour to propogate. The domain I'm trying to set up Google Apps for is an alias of an existing domain - let me explain:
I have mainDomain.com, and this is the name of my domain account on my host, which I cannot change. However, that domain name has expired and is no longer available, so I create a domain alias on the host called aliasDomain.co.za, and choose not to use the main domain DNS. I then set all the MX records, as documented by Google, on aliasDomain.co.za, but it's been about 12 hours with no joy yet.
I suppose I should wait the 48 hours, but if my DNS is wrong, it could be another 48 hours to see if I did fix it. Should what I'm doing work normally, or should I be doing something else?
