Someone is trying to sign up for Apple ID with my email address

want to make sure no one is using my private domain for Apple ID purposes, because the domain is registered to me personally and I don't want to be blacklisted.

They should not be able to ever finish creating an Apple ID, as they need to retrieve the verification email from Apple and respond with a code in it.

Is there a way to request that no Apple IDs be created with emails from that domain?

Again, that is built in to the system. No verification that you have access to the email address you just gave us? No Apple ID.

1. First of all you can hide your domain ownership (your name and address), ask your domain provider

2. Make sure you domain is secure, check your logs

3. Yes create a filter to reject email not create by you.

4. Deactivate your catch all email address.

The links on those emails probably lead to fake versions of Apple's website so they can try to phish for your Apple ID information. :/

No one can use your domain to create an Apple ID.

Because a verification e-mail will be sent to that e-mail address to be verified.

Unless any Tom, Dick & harry can use your domain to create e-mail addresses, all bets are off.

I wonder what the purpose of this would even be... What does some script kid have to gain by spamming requests for fake email addresses?

Don't introduce logic to this. No idea what their business model may be.

I'll guess they have been "attacking" your mail server as well, hoping to breach it and complete the loop. As noted... keep your mail accounts uber secure and let your provider protect you.

It's possible legit addresses return a different error message to them which allows different methods of phishing you and such.

Same thing started happening to me. I have my own domain as well. Weird.
