Create a DMARC Record

A DMARC record is a TXT record in the DNS. The record outlines the DMARC policy for the domain.

We recommend having the minimum DMARC record configuration as below:

v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com

Components:

• v=DMARC1: The version of DMARC.
• p=none: The policy (can be none, quarantine, or reject).
• rua=mailto:dmarc@yourdomain.com: Reporting address for aggregate reports. This email need to be set up by the client and no domain will be provided by Cendyn CRM.

Choose the DMARC Policy (optional)

• p=none: Monitoring mode, no action taken on emails.
• p=quarantine: Emails that fail DMARC are placed in quarantine (spam folder).
• p=reject: Emails that fail DMARC are rejected.

Publish the DMARC Record in the DNS (Optional)

• Access your DNS management console.
• Create a new TXT record.
• The host name should be _dmarc so the full DNS record name will be dmarc.yourdomain.com
• Paste the DMARC record in the value field.
• Save the changes.

Monitor and Analyze DMARC Reports (Optional)

• Regularly check the reports sent to the specified email address.
• Analyze the reports to understand the performance and adjust the DMARC policy as needed.

Adjust the Policy Gradually (Optional)

• Start with a policy of p=none to monitor how your emails are performing without affecting their delivery.
• Gradually move to p=quarantine and then to p=reject as you become confident in the SPF and DKIM setup.
