How do I stop iCloud.com emails from being forwarded to iCloud.co?

Emails for d*********@icloud.com are now being forwarded to d**********@icloud.co

what is icloud.co? Why am I getting these messages constantly? I can send and receive emails from my Gmail to iCloud addresses and vice versa . My email ends in iCloud.com and not icloud.co

Original Title: iCloud.co ?

I’m am very limited on computer or software technology so I can’t answer your questions. All I know is on my iCloud emails I get emails saying that my mail was undeliverable for some reason and I get the email says my icloud.com emails are being forwarded to icloud.co . I have never seen this before and it concerns me. I can send my icloud account emails from my Gmail and I receive them and I can send my Gmail account emails from my iCloud account and receive them. I have no idea what is going on or if someone is accessing my accounts without my knowledge or consent

iPhone, but also when I access my iCloud emails on my PC


Okay.


There is usually a three-digit code with the “undeliverable” message, often but not always 550, and there is usually also some supplemental information action with a reason.


With 550 and most other codes, some of the reasons can include text. The text can be no such user, or verification failed, among many other possibilities.


In addition to the 550 or whatever other three-digit code, and usually also some text, you might see a second code, such as 5.1.1, or 5.1.8, or otherwise.


What is the three-digit code, and what is the text, and if there’s a this.that.otherwise code included, what are these? (If the text of the error message is not sensitive, paste it here.)
