I set up a custom domain autoinfo.cl at Gmail with Route53 AWS. I followed all the instructions described in Google Workspace to set MX records in DNS Manager.
Gmail account works fine to send and receive emails to any other gmail account, but for Outlook or Hotmail accounts only emails can be sent. When I try to send an email from my @outlook.com or @hotmail .com account to any account with the domain @autoinfo.cl I get the following message in the Outlook account:
....
Generando servidor: DS0PR19MB7298.namprd19.prod.outlook.com Servidor de recepción: DS0PR19MB7298.namprd19.prod.outlook.com
[email protected] 10/24/2022 9:47:48 PM - Server at DS0PR19MB7298.namprd19.prod.outlook.com returned '550 5.4.312 Message expired, DNS query failed(ServerFailure)'
....
I don't understand if I need to add another configuration or what is the problem itself, because as I said the domain works fine for any gmail account.
Best regards.
