Mail for domain hosted at iCloud
When Google decided to charge for hosting a unique domain's email, I discovered I could host it at Apple, since I was already paying Apple for an inclusive tier of service. I moved the domain to Apple and now my unique domain email works fine. BUT I started getting error prompts to authenticate the email account requiring me to go back to the Google account. I deleted the email account from my email client, intending to add back the email to the email client redirecting it to what is now hosted by Apple.
My question is this... in trying to add a "new" email (which is working as accessed by a browser session to iCloud) I need to navigate the wizard setup for a new account in the Email app (in this case Spark). I can't seem to use the iCloud wizard button, even using a new app specific password along with my user name for my unique domain. Should I use manual setup and if so, what credentials do I use to direct to the IMAP/SMTP server, for example?
Any assistance greatly appreciated.
