How to add SPF, DKIM, and DMARC
How to add SPF (Sender Policy Framework)
1- Login into your Amazon Route 53 account.
2- Head to your Route 53 Dashboard section and then to the DNS management (Hosted zone).
3- Once you click on the DNS management (Hosted zone) section then try to click on your domain.
4- Select Create a record.
5- Make sure to add your SPF Record type, and Value and leave the Record name part empty because as you can see that your domain is already in place.
For example:
In this case, we whitelisted Zoho’s SPF in our DNS zone.
|
Record Type |
Record Name |
Value |
|
TXT Record |
Leave It Empty |
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.
|
Record Type |
Record Name |
Value |
|
TXT Record |
Leave It Empty |
v=spf1 ip4:169.148.146.23/32 include:zoho.com ~all |
7- Click “Create records” to finish your Amazon Route 53 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 Amazon Route 53, 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 (Amazon Route 53).
1- Select Create a record.
2- Make sure to add your DKIM Record Type, Record Name, and Value.
|
Record Type |
Record Name |
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 “Create records” to finish your Amazon Route 53 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:
- When you directly register on EasyDMARC, our system automatically provides you a DMARC Record upon adding your domain
- 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 Amazon Route 53.
Make sure to add your DMARC Record Type, Record Name, and Value.
|
Record Type |
Record Name |
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 “Create records” to finish your Amazon Route 53 DMARC setup.
