Emails sent to "@icloud.com, @mac.com, @me.com addresses are not delivered to the recipients...

Yep we are having this issue: sending email from our company mail server (gsuites). It has been going on for months now and I have tried to bring it up with apple support and they say that each end user with @mac @me or @icloud email addresses has to contact apple support individually and report the issue. We have had a number of them do this with no success...

when sent an email to my customer from the email service@tianex.com my own domain tianex.com,

it always be rejected with an 550 error,

i tried to unblock it by click the bottom url,but the button never worked

I am seeing the same issue. Order emails placed on teacollection.com are not appering in the mailboxes of @icloud.com, @me.com and @mac.com addresses. I placed a test order wih my own iCloud email and replicated the issue.

Also logs from our servers show the iCloud mail servers responding with a status 250...

Usually when things are undeliverable, we’d have that error and would not get a status 250. Because it’s a status 250, they are in the hands of Apple, and seemingly going to spam somewhere there.

I contacted Apple Support and spoke with an Apple representative who acknowledged this is a known issue as of last week affecting a limited number iCloud Mail users. He could not provide me any another information, but simply confirmed they were aware of the issue and working to resolve it.

Anyone else experiencing this issue?

Bump. I confirmed this is still an issue for emails from teacollection.com. Anyone else experiencing this issue?
