MX Record undefined in self hosting

Not sure if its due to me hosting the SNS in ap-southeast-1, the MX records is not shown here in the verification page.

This is a bug that sometimes happens. I have not yet been able to pin down why exactly.

You can always find the correct records in your AWS setup. The empty spot should be filled with your AWS region!
