Can I use custom e-mail domain to replace existing mail service provider? Meaning easily transfer existing IMAP folders, including large inbox? I understand I'll need to maintain domain registration, but would presumably be able to terminate 3rd party "mail hosting" service.
Yes, you can terminate 3rd party "mail hosting".
To transfer existing mail, I used the Mail app to connect to both then just dragged folders from my 3rd party host (Google) to my iCloud mail account.
