@me.com account is no longer receiving mail
Since the 23rd of January 2024 I no longer receive any incoming mail to my @me.com mail address other than mail from Apple themselves. I've tried every solution that I've seen other than deleting the @me.com account as I know I will lose it if I do so. I am unsure what may have triggered this issue and am desperately looking for a solution as multiple services I use require 2-factor authentication via emails sent to this address that I am no longer receiving. When I tried to send a 'test' email to my @me.com account from a gmail account I received the screenshot below in response:
I've deleted mass amounts of mail to try 'free-up space' even though my iCloud+ has 150gb of free space, I've tried signing in and out of my iCloud, restarting my phone, scanning through and resetting numerous settings, and scouring the apple forums, but nothing seems to fix my very inconveniencing problem.
