How to setup custom domain with DKIM and DKIM2 records

Hi Tejas Acharekar,

Thank you for submitting your question on Microsoft Q&A.
As of my understanding from the question you’re setting up DKIM records for your custom domain and running into some verification challenges. Please follow the below steps how to configure and verify your DKIM records when using GoDaddy as your DNS provider.

Step1:
To obtain your DKIM values from Azure, sign in to the Azure portal and navigate to your Communication Services resource. Within the Email settings, locate the DKIM configuration section. There, you will find two DKIM records, typically labeled DKIM1 and DKIM2, which contain the names and values you need to add in GoDaddy.     

Step 2:

To add the DKIM records in GoDaddy, start by logging in to your GoDaddy account. Navigate to the domain management page and open the DNS settings for email.test.com. Once you’re in the DNS settings, click Add Record, then select CNAME as the record type. 

Step3: 

Create CNAME Records: 

For DKIM1: 

• Type: CNAME
• Name: selector1._domainkey.email.test.com (you'll replace selector1 with the actual name provided by Azure) 
• Value: selector1-azurecomm-prod-net._domainkey.azurecomm.net (the exact value should be from your Azure configuration) 

For DKIM2: 

• Type: CNAME
• Name: selector2._domainkey.email.test.com (replace selector2 as needed)
• Value: selector2-azurecomm-prod-net._domainkey.azurecomm.net (again, use the value from Azure) 

Step 4:

Set the TTL: For both CNAME records, you can set the TTL to around 300 seconds for faster propagation. 

Step 5:

Verify DNS Records: To check if the records were added correctly, you can use tools such as MXToolbox or run below command 

nslookup -type=CNAME selector1._domainkey.email.test.com 

Step 6:

Back in the Azure portal, navigate back to your email domain settings and click on verify. 

Step 7:

DNS updates don’t happen instantly, it can take up to 48 hours for the changes to fully propagate across the internet.
