My Fastmail subscription is up for renewal so I thought I would take another look at iCloud+ Custom Email Domains and see if it would be viable to switch seeing as I already subscribe to iCloud+ for photo storage.
Dominic Lautner detailed a number of shortfalls in Feb 2022 and unfortunately not enough has changed to entice me to switch. Here is an update:
✅ Fixed - As of September’s iOS 16 launch (was available in June as a beta feature) iCloud+ now offers catch-all support for domains
👎 These matters have not changed. iCloud will still prevent you from creating new aliases if you modify the provided MX records and present you with a generic non-helpful error message.
