Why activate DMARC?

Activate DMARC to protect your email against impersonation and spam. Discover how it improves the security and reputation of your domain in a few steps.

Email & Webmail Setup

What is DMARC and why should you activate it?

If you use a custom domain to send emails (for example, info@yourdomain.com), activating DMARC is a key measure to protect yourself from phishing, improve the delivery of your messages and maintain a good reputation as a sender.

Many users don't configure it out of lack of knowledge, but the reality is that it can make a big difference to the security of your email.

How DMARC works and what advantages it gives you

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a policy published in your domain's DNS. It tells receiving servers how to act if they receive emails sent in your name that don't pass SPF or DKIM validation.

Key benefits of activating it

  1. Prevents domain spoofing
    If someone tries to send a fake email as if it came from your domain (for example, a scam), DMARC can block that message or send it directly to spam.

  2. Improves delivery of your legitimate emails
    Services like Gmail, Outlook or Yahoo trust domains with proper authentication more. Activating DMARC can help your emails land directly in the inbox.

  3. Gives you visibility on your domain's usage
    DMARC allows you to receive daily reports on who is sending emails from your domain, so you can detect errors or abuse.

  4. Strengthens security alongside SPF and DKIM
    DMARC is the perfect complement for a solid and up-to-date email authentication policy.

Steps to activate DMARC from your panel

  1. Verify that you already have SPF and DKIM configured
    You can do this from your DirectAdmin or cPanel control panel. If you need help, we have specific guides for that.

  2. Access the DNS zone editor
    From your domain panel, find the option to edit DNS records.

  3. Add a new TXT record
    Use the following basic format:

    Name: _dmarc.yourdomain.com  
Type: TXT  
Value: v=DMARC1; p=none; rua=mailto:reports@yourdomain.com

    • p=none: Monitor only. Recommended for starting out.

    • rua: Address where you want to receive reports.

  4. Save the changes and wait for DNS propagation
    This can take a few minutes to a few hours.

Useful tips

  • Start with p=none policy to monitor without affecting delivery.

  • Review DMARC reports regularly. There are free tools that help you visualize this data.

  • Once you have everything under control, you can change to p=quarantine or p=reject to protect your domain more strictly.

Conclusion

Activating DMARC is a simple but powerful decision to protect your domain, your customers and your reputation as a sender. Don't leave your email to chance: configure DMARC and maintain full control over who can send on your behalf.
