Google Domains

How to add SPF, DKIM, and DMARC

How to add SPF (Sender Policy Framework)


1- Login into your Google Domains account.

2- Head to your My Domains > Manage section.



3- From DNS Zone select Manage Custom Records > Create New Record. 



4- Make sure to add your SPF Record Type, and Data, and leave the Host Name part empty because your domain is already in place.


For example:


In this case, we whitelisted Zoho’s SPF in our DNS zone.



Record Type

Host Name

Data

TXT Record

Leave It Empty

v=spf1 include:zoho.com ~all



5- Additionally, if you’re using sources that only have an IP address you can add the IPs in the same current SPF record.

 



Record Type

Host Name

Data

TXT Record

Leave It Empty

v=spf1 ip4:169.148.146.23/32 include:zoho.com ~all



6- Click “Save” to finish your Google Domains SPF setup.


Note: Having multiple SPF Records for a single root domain is a bad practice and results in authentication failure. If you use multiple sources within your organization, you must have them whitelisted in a single SPF Record.

How to add DKIM (Domain Keys Identified Mail)


It’s the same process for DKIM as well, but we will do some changes for DKIM.


Note: Before diving into steps on how to add DKIM to your Google Domains, it is important to understand that each provider has their own Private/Public Keys that they provide to their customers. In this article, we are focusing on Zoho Mail. We’ve generated the DKIM Public signature from the Zoho Mail portal, and in the next steps, we are going to implement it in our DNS (Google Domains).


1- Try to create a new tab for your DKIM setup.



2- Make sure to add your DKIM Record Type, Host Name, and Data.




Record Type

Host Name

Data

TXT Record

zmail._domainkey

v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC+BeYApQiIf2makHXZzj/vmRNO

The data part contains the public DKIM signature that was generated from the Zoho Mail portal.


3- Click “Save” to finish your Google Domains DKIM setup.


How to add DMARC (Domain Message Authentication Reporting Conformance)


Now from the same place, we can add the DMARC as well.


There are 2 ways to generate DMARC Record:

  1. When you directly register on EasyDMARC, our system automatically provides you a DMARC Record upon adding your domain.
  2. You can also use EasyDMARC’s DMARC Record Generator tool to get a DMARC Record.

After generating DMARC Record, you need to update it in your Google Domains.



Make sure to add your DMARC Record Type, Host Name, and Data.




Record Type

Host Name

Data

TXT Record

_dmarc

v=DMARC1;p=none;rua=mailto:29506ecf8e@rua.easydmarc.us;ruf=mailto:29506ecf8e@ruf.easydmarc.us;fo=1;


Important Note:

It’s always recommended to first start your DMARC Journey in Monitoring mode (p=none). That will help you gather reports, identify & authenticate legitimate email servers used in your organization, and later on advance your Policy to higher levels such as Quarantine or Reject.


After updating, click “Save” to finish your Google Domains DMARC setup.
