I just tonight signed up for a year and also purchased a custom domain name through Zoho. Though I've noticed it says there are no domains configured, and below shows instructions for adding a domain from outside of Zoho and verifying it.

Do I just need to wait a period of time before the domain actually kicks in? Or is there something I need to do in order to proceed?

What I want: I want a custom named email account/mail service hosted through you guys, with the apps provided in the package as well. I also wish to access this custom email inbox from my Phone. I may be able to figure the phone access out, though if a help page already exists, that might be helpful.
