Email plays a very critical role in both of our personal and professional lives. It is how we speak to our loved ones, close friends, and coworkers. It has grown more challenging to verify that the emails you get are reliable and secure, as spam and phishing have become very common. This is where DMARC comes into play! An email authentication technique that aids in preventing email fraud such as phishing, spoofing, for both senders and recipients.

DMARC-ing Your Way to Email Deliverability Nirvana: The Key to Unlocking a Stellar Domain Reputation.

How DMARC works?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol. Its purpose is to provide email domain owners with the opportunity to secure their domain.

It works by building on top of two existing mechanisms: the Sender Policy Framework (SPF) and Domain-Keys Identified Mail (DKIM). These mechanisms allow the domain owner to publish a policy on their domain’s DNS records.

When an email is received by a DMARC-compliant mail server,

  • The server will check the email’s SPF and DKIM authentication results, as well as the “From” address in the email’s header.
  • It will determine if the email is aligned with the domain’s published policy.
  • If the email passes this alignment check and passes either SPF or DKIM authentication, it is considered to be a pass for DMARC evaluation.

Here is an example of a DMARC record published in a domain’s DNS:

“v=DMARC1;p=quarantine;pct=50;rua=mailto:dmarc-agg@example.com;ruf=mailto:dmarc-fail@example.com”

This record tells the receiving mail servers to:

  • Quarantine any messages that fail DMARC evaluation.
  • Send aggregate reports to “dmarc-agg@example.com.
  • Send failure reports to “dmarc-fail@example.com.

The DMARC protocol also includes a mechanism for sending and receiving feedback on messages. The message contains a pass or fail DMARC evaluation, known as aggregate feedback reports and failure reports, respectively.

It is important to note that DMARC is not a standard for encrypting or signing emails. But it is a standard for identifying the authenticity of the sender and preventing unauthorized use of your domain.

How can DMARC help in Email Deliverability?

DMARC is an email authentication protocol. Its purpose is to provide email domain owners with the option to safeguard their domains against email spoofing. The protocol allows the owner of a domain to publish a policy in their DNS records. This record describes the procedures used to authenticate email messages delivered from their domain. This policy can include the use of the Sender Policy Framework (SPF) & Domain-Keys Identified Mail (DKIM) to authenticate email messages.

When an email provider receives an email message, it can check the DMARC policy for the domain of the sender. If the message passes the DMARC check, it will be delivered to the inbox. If the message fails the DMARC check, the email provider can take appropriate action.

In addition to helping with email deliverability, DMARC also provides valuable feedback to domain owners. DMARC allows domain owners to receive reports on messages that pass or fail DMARC evaluation. These reports can help domain owners identify unauthorized use of their domain and take appropriate action.

Implementing DMARC is relatively simple.

  1. Create a DMARC record for your domain: This record specifies the policy for email messages sent from your domain and where to send feedback reports.
  2. Implement SPF and DKIM: DMARC relies on SPF and DKIM to authenticate email messages. You will need to set up these mechanisms for your domain.
  3. Monitor your DMARC reports: You will receive reports on messages sent from your domain, which will help you identify any issues and take appropriate action.

How can DMARC help in saving domain reputation?

Implementing Domain-based Message Authentication, Reporting, and Conformance (DMARC) can help organizations save their domain reputation and improve email deliverability. Here are some of the ways in which DMARC can help organizations protect their domain reputation:

  1. Preventing email spoofing: DMARC is designed to give email domain owners the ability to protect their domain from unauthorized use, also known as email spoofing. Email spoofing occurs when a malicious actor sends an email using a forged sender address that looks like it’s from a legitimate sender. DMARC allows organizations to specify a policy in their DNS records that specifies which mechanisms are used to authenticate email messages sent from their domain. This policy can include the use of the Sender Policy Framework (SPF) and Domain-Keys Identified Mail (DKIM) to authenticate email messages.
  2. Improving email deliverability: When an email provider receives an email message, it can check the DMARC policy for the domain of the sender. If the message passes the DMARC check, it is more likely to be delivered to the inbox. If the message fails the DMARC check, the email provider can take appropriate action, such as moving the message to the spam folder or rejecting the message altogether.
  3. Identifying unauthorized use of a domain: DMARC allows domain owners to receive reports on messages that pass or fail DMARC evaluation. These reports can help domain owners identify unauthorized use of their domain and take appropriate action.
  4. Increasing email server trust: By implementing DMARC, organizations can demonstrate to email providers that they are taking steps to protect their domain from unauthorized use. This can help to increase the trust of email providers in the messages sent from the domain, which can lead to improved email deliverability.
  5. Enhancing domain reputation: With DMARC, organizations can take proactive measures to protect their domain reputation, which can lead to improved email deliverability and increased trust in their brand.
  6. DMARC can be combined with other authentication protocols : DMARC can work in conjunction with other email authentication protocols such as Sender Policy Framework (SPF) and Domain-Keys Identified Mail (DKIM) to provide an added layer of security and validation.

“Implementing DMARC is like putting on your ‘armor’ before heading into battle against cybercriminals.”

By implementing DMARC, organizations can lock the front door and hide the key to their domain. Ensuring that only authorized senders can use it. This improves email deliverability and builds a fortress of trust around your brand. It is a robust and practical solution for email domains to fight against email spoofing, phishing, and other malicious activities.
