Adding DKIM Signature in Zoho mail for your domain Print

Adding DKIM Signature

You can enable DKIM for your domain from Zoho Mail's control panel, after creating the required text record in your domain's DNS manager. The DKIM configuration has three major steps:

1. Generate unique public DKIM Key-value using a default selector in Zoho Mail.
2. Create a TXT record in your Domain's DNS Manager (Domain registrar/ DNS Provider).
3. Validate the selector and Enable DKIM in Zoho Mail.

I.Generate Unique Domain Key in Zoho Mail:

1. Log in to the Control Panel from https://mailadmin.zoho.com as administrator or super administrator.
2. Go to Domains from the left menu, and choose the domain for which you want to configure DKIM. 
3. In the Email Configuration tab, select DKIM
4. Click on Add to add a new selector for the domain.  
5. Provide the selector name, for the domain to be used with Zoho Mail. Ex: zoho
6. Click Add. The selector will be added and a TXT record will be generated and displayed across the added selector.
7. You can copy the text in the TXT value field. 
8. You need to create a TXT record with this value in the DNS Manager before you click Verify.

II. Creating TXT Record in DNS Manager.

1. Login to the domain's DNS Manager where your domain's name server is pointed.
2. Create a TXT record in your DNS with the title as <selector>._domainkey.<yourdomainname.com>
   Ex: zoho._domainkey.zylker.org should be the name of the TXT record if the selector you choose is zoho and the domain name is zylker.org. Replace the text with your custom values without the brackets. 
   If your DNS is hosted with GoDaddy/ WIX/ Squarespace/ Namecheap etc, provide the TXT record name as zoho._domainkey (These providers append the domain name automatically)
3. In the TXT record value, paste the entire content you copied from the text field TXT Record Value in Zoho.
4. Save the TXT record in the DNS Manager.
5. You can check the validity of the DKIM using this DKIM checker.
