Personal domain with iCloud, not showing my email@mydomaine.com
I have changed all DNS details from my domain host to iCloud as I have more space on my iCloud+ subscription. Mails are coming in, but I can't create an email with my domain. I only shows ...@iCloud.com or ...@me.com as possible send-from adresses. Any ideas ?
ps. I use my email@mydomain.com as my apple ID. Is that a conflict ?
