Bluehost

How to add SPF, DKIM, and DMARC

How to add SPF (Sender Policy Framework)


1- Login into your Bluehost account.

2- Head to your Domain section and > My Domains part.



3- Once you click on the My Domains section then try to click on the Manage button.



4- Head to the TXT part and try to Add a Record.



5- Make sure to add your SPF Host Record and TXT Value.



For example:

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


Type

Host Record

TXT 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 Record

TXT Value

TXT Record

@

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


7- Click “Save” to finish your Bluehost 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 Bluehost, 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 (Bluehost).


1- Head to the TXT part and try to Add a Record.



2- Make sure to add your DKIM Host Record and TXT Value.



Type

Host Record

TXT Value

TXT Record

zmail._domainkey

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

TXT Value part contains the public DKIM signature that was generated from the Zoho Mail portal.


3- Click “Save” to finish your Bluehost 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 Bluehost.



Make sure to add your DMARC Host Record and TXT Value.




Type

Host Record

TXT 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 Bluehost DMARC setup.
