First, generate the key in Zoho: log into mailadmin.zoho.in as administrator, go to Domains, select the domain, open the Email Configuration tab and click DKIM, click Add to create a selector (for example, zoho), and copy the generated TXT record. Second, publish the record in DNS: create a TXT record named selector.\_domainkey.yourdomain.com (for example, zoho.\_domainkey.example.com) with the value Zoho provided. For registrars like GoDaddy or Wix that auto-append the domain, enter only zoho.\_domainkey. Verify with a DKIM checker after propagation. Third, enable DKIM in Zoho: return to the Control Panel, click Verify next to the selector, and turn DKIM on so signatures are added to outgoing mail. Common issues: high TTL slowing propagation (up to 12-24 hours), incorrect record values, and copy-paste typos in the public key. Pair with SPF and DMARC.

DKIM configuration happens in 3 steps. Let’s see how these steps unfold to inform recipients if the **email content** was altered in transit. ## Step 1- Generate a unique domain key in Zoho mail - Log in to the Zoho Mail [Control Panel](https://mailadmin.zoho.in/) as an administrator. - In the left menu, go to **Domains** and select the domain to configure DKIM. - In the **Email Configuration** tab, choose **DKIM**. - Click **Add** to create a new selector. - Enter a selector name (e.g., ‘zoho’) and click **Add**. - _Copy the TXT record generated_. - Add this TXT record to your [DNS Manager](https://beehosting.pro/what-is-a-dns-manager/), then click **Verify** in Zoho Mail. [![email security](https://media.mailhop.org/duocircle/images/2024/10/spf-record-generator-4923.jpg)](https://media.mailhop.org/duocircle/images/2024/10/spf-record-generator-4923.jpg) ## Step 2- Creating TXT record in the DNS manager - Log in to your domain’s DNS Manager. - Create a new [TXT record](https://www.digicert.com/faq/dns/what-is-a-txt-record) with the name: **.\_domainkey.**. Example: If your selector is ‘zoho’ and your domain is ‘domain.org, the name would be \`zoho.\_domainkey.domain.org.\` (For providers like GoDaddy, WIX, etc., use \`zoho.\_domainkey\`, the domain name will be **added automatically**.) - _In the TXT record value, paste the content you copied from Zoho_. - Save the TXT record. - Use a [DKIM checker](/resources/dkim-checker) to verify the setup. ## Step 3- Turning on DKIM for the domain - _After successfully validating DKIM on the third-party site, log in to the Zoho Mail Control Panel_. - Click **Verify** next to the specific selector. - The text record will update to **Verified**. - You’ll get a prompt to enable DKIM right away or later. - If you enable DKIM immediately, [DKIM signatures](https://docs.mapp.com/docs/dkim-signature) will be added to all [outgoing emails](https://www.zoho.com/mail/help/adminconsole/outgoing-rules.html) from your domain. ## Troubleshooting common DMARC issues ### Setting TTL [TTL (Time To Live)](https://www.geeksforgeeks.org/what-is-time-to-live-ttl/) in DNS controls how long it takes for DNS changes to take effect. If you set a high TTL value, like 24 or 48 hours, updates to records like TXT or [SPF](/resources/what-is-spf) may take longer to propagate, **sometimes up to 12 to 24 hours**, depending on the TTL you choose. [![TTL in DNS controls](https://media.mailhop.org/duocircle/images/2024/10/spf-validator-4.jpg)](https://media.mailhop.org/duocircle/images/2024/10/spf-validator-4.jpg) ### Inaccurate values [SPF records](/content/spf-records) may need to be added differently depending on which provider you use. To ensure you get proper guidance on adding a DKIM record, you can check the ‘help’ pages or contact your **provider’s support team**. ### Spelling mistakes _Make sure you’ve copied the correct information from the Zoho Setup pages_. For [DKIM](/resources/what-is-dkim), copy the entire key and use it as the value of the TXT Record. The TXT Record name should follow the **recommended naming rules**. ## Final words After configuring DKIM keys for Zoho, you should also enable [DMARC](/resources/what-is-dmarc). While it is optional, we recommend you also start receiving [DMARC reports](/content/dmarc-report). We can help you uncomplicate and analyze aggregate and forensic reports so that you can make the right adjustments to your TXT records if needed.
