This post is for those who want to use a domain name bought before the google apps account creation. Indeed, if you buy a domain name with the google apps interface, everything will be working fine. The trick is to manually set up the correct DNS configuration. So either you use the DNS service provided by your registrar (you lucky guy !) or you can use a free DNS service such as
xname.org. Here is the correct DNS stuff you need to add:
@ A 72.14.207.121
@ A 64.233.179.121
@ A 66.249.81.121
- CNAME records (don't forget the trailing dot at the end)
www CNAME ghs.google.com.
calendar CNAME ghs.google.com.
start CNAME ghs.google.com.
mail CNAME ghs.google.com.
docs CNAME ghs.google.com.
sites CNAME ghs.google.com.
- MX records (don't forget the trailing dot at the end)
MX 10 aspmx.l.google.com.
MX 20 alt1.aspmx.l.google.com.
MX 30 alt2.aspmx.l.google.com.
MX 40 aspmx2.googlemail.com.
MX 40 aspmx3.googlemail.com.
MX 40 aspmx4.googlemail.com.
MX 40 aspmx5.googlemail.com.
If you have a blog on blogger, e.g., yourblog.blogspot.com, you can also add a blog subdomain, just add this line in your CNAME records (of course, you also need to tell blogger about this by digging into the configuration interface) :
blog CNAME ghs.google.com.
Hope that helps !
