What is DMARC?

DMARC, or Domain-based Message Authentication, Reporting, and Conformance, is an email validation system that protects your domain from unauthorized use, commonly known as email spoofing. 

The purpose of DMARC is to enable email domain owners to set policies that define how email receivers treat emails that don’t authenticate against the domain's SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) standards. This includes reporting mechanisms that inform the sender about emails that fail DMARC checks. By using DMARC, organizations can improve the security of their email communications, enhance deliverability, and protect their brand reputation from fraudulent activities.

How Does a DMARC Record Look?




Time to live (TTL)





A DMARC record is a TXT record published in the DNS for your domain. A typical DMARC record looks something like this:

v=DMARC1; p=reject; rua=mailto:reports@example.com; ruf=mailto:forensic@example.com; fo=1; adkim=r; aspf=r; pct=100; sp=none; rf=afrf; ri=3600

Here’s a breakdown of what this includes:

• v=DMARC1 indicates the DMARC version.
• p=reject directs receiving servers on how to handle emails that fail DMARC checks (options include none, quarantine, or reject).
• rua=mailto:reports@example.com specifies where aggregate reports of DMARC failures should be sent.
• ruf=mailto:forensic@example.com is for sending forensic reports.
• fo=1 defines the conditions under which reports are generated.
• adkim=r and aspf=r set alignment modes for DKIM and SPF, respectively, to be relaxed or strict.
• pct=100 means applying the DMARC policy to 100% of failing emails.
• sp=none sets the policy for subdomains.
• rf=afrf defines the format of forensic reports.
• ri=3600 sets the interval for sending reports in seconds.

  • www is the subdomain and is an identifier of the record.

  • CNAME is the DNS record type.

  • com is the value of the record. That means www will resolve to the IP address of the domain abc.com.

  • 3600 is TTL (time to live) is the expiry time of the CNAME record. It's expressed in seconds. Here 3600 means that the records will be updated after each hour.

By customizing these values, domain owners can control how their email traffic is handled and monitored, enhancing their overall email security strategy.

Email automation FAQs- Smartlead

DKIM (DomainKeys Identified Mail) is an email authentication method that helps protect email senders and recipients from email spoofing and phishing attacks. DKIM allows you to attach a digital signature to email headers, verified via a public key in the sender’s DNS, to confirm authenticity. SPF (Sender Policy Framework) is an email authentication method used to prevent spammers from sending messages on behalf of your domain. It authorizes mail servers to send emails on behalf of your domain. It checks incoming emails against this authorization, blocking spoofing and improving email legitimacy.
