This article covers the SPF and DKIM authentication processes for Zoho Sign and how they are managed in Valimail While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

This step is necessary for Zoho Sign to recognize your domain, and generate a key (hostname, value) for that domain.

1. Navigate to Settings -> Account settings -> Email domain verification status.

2. Click Verify now.

3. Enter your domain name. For example, if your email is [email protected], the domain name you'll have to enter is zylker.com.

4. Click the Generate Key button. This will generate a hostname and value.

In this step, you need to publish your domain's public key as a TXT record in your DNS Manager. Every outgoing email from Zoho Sign will have a signature added to its header generated using the private key of your domain. Your recipient's email server will validate emails sent from Zoho Sign using the public key published in your DNS record.

Important: If you manage DKIM in Valimail for your domain, you will need to add the TXT DKIM key on your domain's Configuration page in Valimail Enforce.

1. Login to your DNS Manager.

2. Select the TXT Method tab in the Domain Verification page.

3. Create a TXT record in your DNS with the title as the hostname. For example, zoho._domainkey.zylker.org should be the name of the TXT record if that was the hostname provided.

4. In the TXT record value, paste the content you copied from the Value field in Zoho Sign.

5. Save the TXT record in the DNS Manager.

6. Go to Zoho sign and click the Next button in the step-2 (Add TXT record).

1. Ensure you have completed adding the TXT record in the DNS Manager.

2. Click the Verify Domain button.

3. If the entry has been added correctly, your domain would be marked as verified and emails sent from Zoho Sign will be signed and verified using the key pairs.

4. You should not remove this TXT record from your domain hosting console as long as you continue to use that email address in Zoho Sign. If not your email domain will be marked as not verified again and your emails may land in spam.
