also, what should my mail link be?
The link I posted was http://mail.google.com/a/46degrees.co.nz, which goes to a Gmail sign up.
Typing it without the http:// like you did results in the "Sorry, you've reached a login page for a domain that isn't using Google Apps. Please check the web address and try again. Learn more" message.
Neither of them the desired result, either way : /
Also, I notice that Dreamhost's wiki says that the mailbox URL should be "http://mail.example.com", however Google Apps gives the format as "http://mail.google.com/a/example.com" in its Dashboard. Though neither of these work for me; http://mail.46degrees.co.nz gives a Google 404, and http://mail.google.com/a/46degrees.co.nz goes to the sign up for Gmail screen I posted the pic of earlier.
The other thing is I bought my domain from another registrar but the site and mail is hosted with DreamHost, is this relevant?
