iCloud custom email domain stopped receiving mail

For the last two days, after zero issues for several months since setting up, one of my custom domains has not been receiving mail. This is across all devices as well as iCloud.com. The other custom domain is not impacted. I can still send outgoing mail from the domain in question. No DNS settings have changes.

After 24 hours, some senders are receiving the following NDR:

451 4.3.0 <name@custom.com>: Temporary lookup failure

Has anyone had any luck removing a custom domain and re-adding it?

This happened to me, even after the email was working for a while. I went to the custom domain, iCloud page on my browser and found the setting for "allow all incoming messages" was turned off. Odd, but once I turned it on, things are working again. I hope this helps.

Hi there bdh4136,

Even though the title of this article doesn’t mention iCloud Custom Domain, it’s still an iCloud mail issue. Please follow the steps under "If your recipient doesn't receive your message” here: If iCloud Mail isn't working - Apple Support

If that doesn’t resolve the issue, you’ll need to contact Apple Support directly: Get Support

We hope that helps!
