Iphone issues

Hi there

I've recently signed up to Zoho Mail, and am trying to set up mail on my iPhone. 

I have a domain name linked to you for mail hosting and I want emails sent to this domain to be received on my iphone. I have tried extensively to follow your guides, but I am having no luck. Either username and password is not recognised or the verification of smtp times out. 

When setting up the iMAP am I to use my zoho.com com account or do I use steve (at) domaineditedfor privacyreasons (dot) com as my username? 

Any help would be greatly appreciated.

Many thanks

Steve
