Adding MX, SPF, and DKIM Records:

1. MX Records:
   • Log in to your domain provider’s DNS Manager.
   • Navigate to the MX records page and remove any existing entries.
   • Click “Add Record” and enter the MX records data provided on the DNS Mapping page.
   • The MX values should be:
     • Host/Domain: @ or Blank
     • Address/Mail Server/MX Entries/Value: mx.zoho.com.
     • Priority: 10
     • Add two more MX records with priority 20 and 50, pointing to mx2.zoho.com. and mx3.zoho.com. respectively.
   • Save the changes.
2. SPF Record:
   • Navigate to the TXT records tab in the DNS Manager.
   • Click “Add TXT Record” and enter the SPF value: v=spf1 include:zcsend.net include:servers.mcsv.net include:zoho.com ~all
   • Save the changes.
3. DKIM Record:
   • Log in to your Zoho Mail account as a Super admin.
   • Go to Control Panel and select Email Authentication. Choose DKIM from the drop-down.
   • Edit the domain name and selector (add “zoho” as the selector name if not added already).
   • Copy the entire text from the TXT record value field.
4. Add DKIM Record:
   • Log in to your DNS manager.
   • Add a TXT record with the following details:
     • Host Name: zoho._domainkey
     • TXT Record Value: (Paste the copied DKIM record from your Zoho Control Panel)
   • Save the changes.

Verification:

• Go back to the Zoho Control Panel and click “Verify” to ensure your records are correctly set up.

Please note:

• The specific terminologies might vary based on your domain provider’s interface.
• Ensure that you have only one SPF record to avoid email delivery interruptions.
• It might take some time for the DNS changes to propagate across the internet.

After the records have propagated, you should be able to receive emails from external accounts into your Zoho inbox. If you encounter any difficulties or if the issue persists, don’t hesitate to reach out to Zoho’s customer support for further assistance.

Certainly, let’s delve a bit deeper into the process of configuring MX, SPF, and DKIM records to ensure proper email delivery to your Zoho inbox.

MX Records (Mail Exchange Records): MX records play a crucial role in directing incoming email messages to the correct mail servers. These records specify the mail servers responsible for receiving email messages on behalf of your domain.

• Priority: Each MX record has a priority assigned to it. Lower numbers indicate higher priority. Email servers will attempt to deliver emails to the server with the lowest priority first. If that server is unavailable, it will try the next one with a higher priority.

SPF (Sender Policy Framework) Record: SPF records help prevent email spoofing and phishing by specifying which IP addresses or domains are authorized to send emails on behalf of your domain. It’s essentially a list of servers that are allowed to send emails using your domain name.

• Include Mechanism: The “include” mechanism allows you to include other domains or IP ranges in your SPF record. In your case, you’ve included zcsend.net, servers.mcsv.net, and zoho.com in your SPF record.

DKIM (DomainKeys Identified Mail) Record: DKIM is a cryptographic method that adds a digital signature to your outgoing emails. It helps verify that the email was indeed sent by the domain it claims to be from and that it hasn’t been altered during transit.

• Selector: DKIM uses a “selector” to differentiate between different sets of keys for a domain. In your instructions, you’re using the “zoho” selector.

Verification:

• After adding the records, you should allow some time for these changes to propagate across DNS servers worldwide. This process can take a few hours to up to 48 hours, depending on your domain provider.

Additional Tips:

• Make sure there’s only one SPF record for your domain to prevent email delivery issues. Multiple SPF records can cause validation to fail.
• Ensure the TTL (Time to Live) value for your DNS records is set to a low value when making changes. This ensures that the changes take effect more quickly.

Toolkit by Zoho Mail:

• The Zoho Mail Toolkit is a free lookup tool that helps you perform DNS-related lookup queries. You can use it to check the status of your MX, CNAME, and other DNS records.

Remember, while I can provide information and guidance, specific steps might vary based on your domain registrar’s interface. If you encounter any issues or have questions, don’t hesitate to reach out to Zoho’s support or your domain provider’s support for assistance tailored to your situation.
