Can't Receive Email on Custom Domain
Published
I recently changed registrars and have been unable to receive email on my custom domain since. I have confirmed my DNS settings are correct. I've tried sending emails from both iCloud and Outlook.com to my custom domain and they bounce back with the following error:
The following organization rejected your message: mx1.mailbox.org.
I tried removing and re-adding my custom domain to mailbox and I'm still seeing the same problem. I've opened a ticket with Mailbox but they say it could be two weeks before they get back to me.
Any ideas?
The same problem 
No connection
Real-time notifications may not work
What is the full error message? Sender address rejected: Domain not found?
Maybe it's this issue:

Hi,
thank you for your message. Your domain has not been propagated to all of our DNS-resolvers. This was the reason the e-mail could not be sent to your domain. Our administrators have now fixed it and you should be able to receive e-mails again.
We do have a lot of tickets at the moment, so in some cases it can take up to two weeks until we can respond to a ticket. Of course we are prioritizing the tickets and make sure that time sensitive issues like yours are worked on as soon as possible.
I apologize for the inconvenience and hope that you enjoy your mailbox account.
With kind regards
