How to Activate DKIM Key in Salesforce

‍

Here is a step-by-step tutorial on how to activate the DKIM key in Salesforce:

1. Go to Setup on the top right.
2. Search for DKIM Keys in the Quick Find.
3. Make a new key by clicking on the Create New Key button.
4. Fill in the DKIM Key Details.
5. Enter details like your Domain, Selector, and Alternate Selector. (Hover over the "i" button for context)
6. You can select the Key size based on the security regulations of the organisation.
7. Wait till the keys get published.
8. After the keys get published, you will see CNAME records that are available to be copied to your DNS for your domain.
9. Salesforce has published the TXT records for this DKIM key to your DNS provider. 
10. Now move to your DNS Provider and Select Your Domain (Ex: "storylane.io")
11. Navigate to DNS Settings and Add the Primary CNAME Record: 
12. For example, CNAME Record shows: <st1._domainkey.storylane.io IN CNAME st1.jpdc2t.custdkim.salesforce.com>some text
    • In the "Name" field, enter the Host Name for the primary CNAME record (Ex st1._domainkey.storylane.io)
    • In the "Content" field, enter CNAME Record (Ex- st1.jpdc2t.custdkim.salesforce.com)
    • Repeat the process and Add an Alternate CNAME Record.
