How to create a DMARC record

In this article, you'll learn how to create a DMARC record for the DMARC policy application of "none," as well as how to configure a domain to receive reports on multiple autoresponders.

What you'll need:

• A custom email address and a domain name

I. Steps to add the DMARC record

1. Access hosting provider: Log in to your domain registrar or hosting provider's dashboard and navigate to the DNS settings.
2. Create the record: Start the process of creating a new DNS entry and choose the TXT type. You will then need to enter the following:

3. Name your record _dmarc; the domain name is automatically added to the name, resulting in the full name _dmarc.yourdomain.com. If the domain name is not automatically added at the end, you should then name the record _dmarc.yourdomain.com instead of just _dmarc.

4. Enter the value of your record. Here's an example value for DMARC:

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

For example:

If your email address is "example@example.com", you need to add the value "v=DMARC1; p=none; rua=mailto:example@example.com".

Notes:

• Adding a DMARC record generates a daily report sent by email providers. These DMARC reports are sent to the email address you set to the value "rua" when adding the DMARC record.

To avoid flooding your main inbox, we recommend creating a dedicated email address specifically for these reports. All you need to do is set up the notification email on the "rua=mailto:example@example.com" part when adding the DMARC record.

• Once you have created the DMARC record, you can verify that it has been added correctly by visiting the website https://mxtoolbox.com/dmarc.aspx

Important:

• A DNS zone can contain several TXT records, but there must be only one DMARC record per domain. Having multiple DMARC records on the same domain can cause conflicts and prevent the policy from working correctly.
• Adding a DMARC record helps to ensure that all legitimate emails from your domain are authenticated correctly by receiving email servers.
• You will receive DMARC reports to help you ensure that all legitimate emails are identified and pass authentication.

II. Configure a domain for multiple autoresponders

If you want DMARC reports to be sent to multiple autoresponders or multiple email addresses, it is possible to modify the value of your DMARC record to include multiple recipients. The following example illustrates this configuration:

v=DMARC1; p=none; rua=mailto:youraddress@yourdomain1.com,mailto:yourdomain2.com

In this example:

• yourdomain1.com   and yourdomain2.com each represent a distinct domain or service that receives the DMARC reports. This can correspond to different autoresponders, monitoring services, or internal teams responsible for email security and deliverability.
• The rua  directive (Reporting URI for Aggregate reports) lists all email addresses to which aggregate DMARC reports will be sent. Each address must be separated by a comma, without spaces.

Thanks to this configuration:

1. Centralization of reports: all DMARC reports generated for your domain will be automatically sent to each of the listed addresses, which allows for complete and coordinated tracking.
2. Multi-service tracking: if you use multiple sending services or autoresponders for your domain, each service can receive the necessary reports to analyze deliverability and detect fraud or spoofing attempts.
3. Better visibility: By distributing reports to multiple recipients, you ensure that all concerned teams like marketing, security, and IT have the information to react quickly in the event of a problem.

Note: Even if you add multiple recipients for reports, you must still have only one DMARC record per domain. Adding several distinct DMARC records on the same domain can create conflicts and prevent the proper receipt of reports.

In summary, by listing several addresses in the rua  directive, you can share DMARC information securely and in a coordinated manner while maintaining a single official DMARC configuration for your domain.
