G Suite Gmail (MX/SPF) records

Posted in Smarter Mail on Nov 07, 2019

If you want to use G suite as an email solution, then you need to update G-suite mail records to your Domain provide.

To do this, you need to sign in to your domain host and direct the email for your domain to the G Suite servers. It’s like registering your new address with the post office when you move so that your mail gets delivered to the right place.

Add the G Suite MX records

To direct your email to your G Suite account, you must add new MX records to your domain. Add the MX records shown in the table below in one step with synthetic records. With synthetic records you can optionally add additional features that you select, when you add 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: The values are the G Suite mail servers. We include 5 servers in case one fails or requires maintenance.

Prevent email spoofing with SPF records

Protect against forged emails that appear to come from your domain Spammers might send emails that appear to come from your domain. This is called spoofing. You can add a Sender Policy Framework (SPF) record to your domain host to help your recipients know where emails from your domain should be coming from and that they aren't spoofed.

Add SPF TXT record to your domain host

Create a TXT record with these values:

Name/Host/Alias            Time to Live (TTL)                          Value
     @                          3600                      v=spf1 include:_spf.google.com ~all.

Add multiple servers to an SPF record

Your domain can only have one SPF record. However, you can update your SPF record to include all your mail servers. For example, if you set up an outbound email gateway, your SPF record includes the Gmail server address and the outbound gateway SMTP server address.

To add a mail server to an existing SPF record, enter the server's IP address before the ~all argument.

Use the format ip4:address or ip6:address as shown in this example:

v=spf1 ip4:172.16.254.1 include:_spf.google.com ~all

To add a mail server's domain, use an include statement for each domain. For example:

v=spf1 include:serverdomain.com include:_spf.google.com ~all

Note: - Your New SPF record takes effect within 48 hours.
