I'm sure this is a dead end, hopefully not, but cloudflare is really driving me batshizz crazy with my desire to use a cloudflare domain, which was promoted via iCloud. If it's not a dkim error then its a spf record error or something else. Finally, after updating all dns records, multiple times, I finally get the error indicating that I need to provide a security code for an email address that is under the new domain that I'm attempting to add to icloud to host the email...really? Soooo....how would I obtain a security code for a domain that I do not yet have the ability to check the email, obviously. Driving me nuts. Any takers on this one?
