Configuring MX Records / DNS for G Suite
First, you can edit the MX Records for your domain in your account by navigating to “My Services > DNS Records”. On this page you’ll click “Modify” for the domain you want to add the records for. You’ll see the MX record section at the bottom. There is also a button that will give you more fields to add additional MX Records. Make sure once you’re done adding the records to click update.
Validating The Service
Google requires you to validate the domain to use their service with a validation MX record. You will notice that you are not able to add more than 5 MX Records at one time.
What you need to do is use a TXT record from google to validate the domain instead. You can then add that TXT Record by navigating back to the “Modify” page for your domain and clicking on “TXT”. You will add the value at the bottom and then let Google know that you’ve added it. It may take up to 5 minutes for Google to be able to see that record.
How to Add the MX Records
You’ll also notice with Google’s instructions that you need to set the priority for the first MX Record at 1. This isn’t actually necessary, what’s important is the Priority Order. Since ours start at 5 their MX record with a priority of 1 will be set to 5 the next one at 10 and so on.
Their checker will not see this as correct but mail will start flowing normally regardless, as long as the order is correct.
