iCloud Hide My Email not delivering forwarded emails with 550 5.7.1 error

Hey there! Starting today, I am experiencing some issues with the iCloud Hide my Email service.


I noticed that I was not receiving authentication codes on my iCloud “forward to” email. I have multiple hide my email iCloud mails forwarding mails to my actual address, and I never had any problem.


So out of curiosity I double checked by using another email of mine to send a test mail to one of my iCloud addresses, and it got back to me with this error message:


“This is a system-generated message to inform you that your email could not

be delivered to one or more recipients. Details of the email and the error are as follows:



: 550 5.7.1 [MTA-HB102] Message rejected due to

  local policy; if you feel that your email was rejected in error, please

  forward a copy to [email protected].”


I tried to look online, and I’ve seen other people having the same issue, but I wasn’t able to find a solution.


I also tried to send emails to multiple of my hide my email address, but none of them work.


Please let me know if you have a solution, and thanks for your time
