DKIM & SPF Setup for Zoho Mail

To set up or edit your SPF record, you will need to add: include:zoho.com

Edit existing SPF record

1. Log in to your DNS hosting provider
2. Look for a TXT containing v=spf1
3. In your existing SPF record, you will append include:zoho.com
4. For example, if your existing record looks like v=spf1; mx; ip4:1.2.3.4; you would add the above include as follows v=spf1; mx; ip4:1.2.3.4; include:zoho.com

Create a new SPF record

1. Follow the instructions from our How to Create a New SPF Record Guide.
2. In the Value field, enter: v=spf1 include:zoho.com ~all and Save the TXT record.

Records for Subdomains

If you are creating a record for a subdomain, you will want to make sure that you specify the sub part of the domain in the Host/Name/Alias field for most DNS providers.

1. Enter the sub part of the domain, for example if the subdomain is mail.mxtoolbox.com you would want to enter mail into that field.

SPF and DMARC Alignment

By default, Zoho Mail will set you up for sending using one of their domains for the return-path address. This domain will NOT pass SPF Alignment. At this time, this provider does NOT provide any mechanism that will allow SPF Alignment to pass. You need to enable DKIM for this provider to ensure your email will pass DMARC Compliance.

How to Set Up/Modify DKIM for Zoho Mail

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

1. Generate unique public DKIM Key value using default selector in Zoho Mail

2. Create TXT record in your domain’s DNS Manager (domain register/DNS provider)

3. Validate selector and enable DKIM in Zoho Mail

To complete the first step, follow these instructions:

1. Log in to control panel for Zoho Mail using Administrator credentials

2. Select Email Authentication and choose DKIM to navigate to DKIM configuration page

3. Click Edit icon across domain you want to configure DKIM

4. Click Add Selector to add new selector for domain

5. Provide selector name for domain to be used with Zoho Mail (e.g., zoho)

6. Click Save

7. Copy entire TXT record value to create necessary TXT record in DNS manager (second step above; zoho._domainkey.yourdomain.com)

As a user of this outbound email provider, Zoho Mail customers are afforded DKIM signing because it supports that mechanism. By utilizing Zoho Mail’s self-service portal, you can manually set up DKIM at your convenience via TXT records mentioned above. Overall, this Zoho Mail product provides beneficial components (e.g., DKIM signing, custom DKIM records, self-service set up with TXT records) that result in a streamlined process.
