@nprofile1q... @nprofile1q... As I understand things, Apple has two flavors of “hide my email”. One is used with “Sign in with Apple”. If you use the hide my email option when signing in, it links that email to a list of allowed domains that can send mail. These addresses are “@privaterelay.appleid.com”. If you setup a regular “hide my email” address, it will be an “@icloud.com” address and not be limited to domains that can send.
