How to add SPF, DKIM, and DMARC

How to add SPF (Sender Policy Framework)

1- Login into your NameCheap account.

2- Head to the Domain List.

3- Then to Advanced DNS.

4- Select Add New Record.

5- Make sure to add your SPF Type, Host, and Value.

For example:

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

Type	Host	Value
TXT Record	@	v=spf1 include:zoho.com ~all

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

 

Type	Host	Value
TXT Record	@	v=spf1 ip4:169.148.146.23/32 include:zoho.com ~all

7- Click “Save” to finish your NameCheap 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 need to 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 on your NameCheap, 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 (NameCheap).

1- Select Add New Record.

2- Make sure to add your DKIM Type, Host, and Value.

Type	Host	Value
TXT Record	zmail._domainkey	v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC+BeYApQiIf2makHXZzj/vmRNO kmQXqVu4aKYcNqj5ANGbJNYGROfo63TTlu2KUWootMQ1nHiiKfFODPO6LjUwn3zp mRv7ONmcm40QOysLrv5cGk+l9letBM7DnVqrvHsMOMHVv1q87fy1n4DuqDM/cVKM qaAExyY+yAKZfUfuRQIDAQAB

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

3- Click “Save” to finish your NameCheap 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 NameCheap

Make sure to add your DMARC Type, Host, and Value.

Type	Host	Value
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 NameCheap DMARC setup.
