After a further look, this is not quit as cool as I thought. You must have your Domain name registered, and then iCloud+ will act as the SMTP and IMAP server for up to three email addresses per person on a family account. This saves the cost of a web hosting site but you still have to pay for domain registration. As site hosting prices keep climbing, this could be an attractive alternative for individuals, families, and micro businesses. To satisfy my curiosity I will continue to explore this feature.
