Firstly, what is a MX Record? It is a record in the Domain Name System (DNS). A mail exchanger record (MX record) specifies the mail server responsible for accepting email messages on behalf of a domain name. In this case, the Google Gmail servers. It is possible to configure several MX records, typically pointing to an array of mail servers for load balancing and redundancy which is why Google lists a set of 5 records to be entered into your domains DNS.
To configure your DNS with the new MX records you must have access to your domain DNS.
We’ll cover that separately and today we will assume you already have access and are ready to update the MX records.
Values for G Suite MX records
|Name/Host/Alias||Time to Live (TTL*)||Record Type||Priority||Value/Answer/Destination|
|@ or leave blank||3600||MX||1||ASPMX.L.GOOGLE.COM.|
|@ or leave blank||3600||MX||5||ALT1.ASPMX.L.GOOGLE.COM.|
|@ or leave blank||3600||MX||5||ALT2.ASPMX.L.GOOGLE.COM.|
|@ or leave blank||3600||MX||10||ALT3.ASPMX.L.GOOGLE.COM.|
|@ or leave blank||3600||MX||10||ALT4.ASPMX.L.GOOGLE.COM.|
Note: Some domain hosts use different labels for the name and value fields, and some hosts also require a trailing period at the end of the server name.
For more information you can refer the Google support page.
Now you are all set to receive email into your G Suite account.
Next you should add the Google SPF Record.
