Inbound mails are bounced (Custom Domain)

I've been receiving more and more messages from people/companies sending me mails and the mails are not being received.

They receive a bounce mail with: 554 5.7.1 [CS01] Message rejected due to local policy.

The mails are legit and Apple Support got no clue.

Anyone got a clue.

Bounced email: [HM08] Message rejected due to local policy. Searching for this on the apple site or on the web doesn't state what is going on. About a week ago, apple mail servers started rejecting email from my server to individuals (including myself) that I have been sending email to for many many years. The web document for HM08 is content free with regard to this "local policy" change. So Apple, please: 1) Please provide useful content in URLs you mention in failed mailed. 2) What exactly is "local policy"? This also needs to be documented. 3) What changed in the past week or so? 4) How can we get this back working again? Thank you. Mark L*** Previous posting from someone that went unanswered: Bounced email: [HM08] Message rejected due to local policy. Hi - I can't get hold of anyone at the postmaster account for Apple whom I emailed earlier in the week. I have a mail server using DKIM and SPF, and sending mail successfully to loads of other domains / mail servers. Apart from the disreputable uceprotectl3 list which has blacklisted the entire subnets for the hosting company I am using (Digital Ocean), I am not on any blacklists. From the server, icloud will accept emails from one domain but not another (I setup an icloud email address to test). The smtp error message refers to local policies, but links to a generic spam advice posting. I am not sending unsolicited email, and in fact the emails are human replies to ones received from icloud customers. Unfortunately the smtp error message in the logs doesn't say anything useful like what actual policy is causing the message being rejected. Does anyone know what we can do to get Apple to deal with or help us diagnose mail delivery issues like these? Posted on Mar 11, 2023 4:37 AM [Edited by Moderator]

When I send mails using Hide My Email, it gets rejected Whenever I send a mail using the Hide My Email option in the From field, it gets bounced on the receiving end with the message quoted below. It happens without exception, regardless of the receiver's address or domain. This only happens when sending from the Mail app on the Mac. Mail apps on my iPad and iPhone do not present this problem and are received correctly. I have all the latest OS versions on all my devices and I'm logged on with same Apple Id on all. Anybody knows what the reason might be? Rejection message example: pv37p00im-ztdi11090501.me.com rejected your message to the following email addresses: Receiver_Name Your message wasn't delivered because the destination email system rejected your message for security or policy reasons. For example, the email address might only accept messages from certain senders, or it might not accept certain types of messages, like those larger than a specific size. Contact the recipient (by phone, for example) and work with them and their email admin to determine what policy or setting blocked your message and what you should do to make sure that future messages from you won't be rejected. For more information, see Status code 5.7.1. pv37p00im-ztdi11090501.me.com gave this error: Delivery not authorized -----[message headers I omit here to save space]---- Action: failed Status: 5.7.1 Diagnostic-Code: smtp;550 5.7.1 Delivery not authorized [Email Edited by Moderator]

Hey there MBijen,

We depend on emails ourselves, and can understand needing them to work without any issues. This link shows the next steps to take as you're not receiving your iCloud emails: If iCloud Mail isn't working Please keep in mind that the last step in the link would be to contact Apple Support.

Cheers!
