Setting up Google Domains DNS to work with Mailgun MX Records

Question

I am trying to use Mailgun to receive emails at subdomains of my email. Like at [email protected]. I added the MX records as instructed by Mailgun, however I cannot get it to completely verify. The MX records stay orange with an "!".

I use Google Apps for the main domain example.com, but not for any subdomains.

What do you think I can do to get Google Domains & Mailgun to agree on what MX records to use?

Answer 1

In Google DNS, you need to use the same entry, but with two "sub-entries" for the MX records. Enter the first mail server:

mxa.mailgun.org

Then click the '+' symbol to the right of the field. When the second text field appears, enter the second MX record:

mxb.mailgun.org

Google will automatically prioritize both of entries at 10.

Here is how it appears on the screen: .

Answer 2

For Google Domains, you need to add the subdomain bob.stage MX records as a Custom resource records.

In the name field, you'll need to add bob.stage and in the Mail server field, add mxa.mailgun.org. Same thing for mxb.mailgun.org.
