This article covers the DKIM authentication processes for Zoho Assist 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.

Note: Zoho Assist does not send SPF aligned emails and does not (as of present time) support SPF alignment.

To verify your email domain ownership using DKIM in Zoho Assist, you need to complete the three steps as mentioned below:

Add domain name

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

1. Navigate to Settings -> General -> Email Configuration.

2. Click Domain verification.

3. Click Add & Verify New Domain.

4. Enter your domain name. For example, if your email ID is [email protected], the domain name to be entered is zykler.com

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

Add TXT record

In this step, you need to publish your domain's public key as a TXT record in Valimail, a step which is detailed in the next section. Every outgoing email from Zoho Assist 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 Assist using the public key published in Valimail.

6. After the DKIM key is published in Valimail Enforce, go to Zoho Assist and click Verify Now.

Once you establish that Zoho Assist is an authorized sender for your domain, you will need to add the service in your Enabled Senders.
