Reading. Books on the table

An essential first step in protecting your domain’s email system and thwarting email spoofing and phishing is publishing a DMARC record. DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol. It aids to protect your domain name from unauthorized use and illegal intrusion.

Using email for both personal and business needs is essential. It is nevertheless one of the simplest targets for cybercriminals. Also, these criminals use email spoofing and phishing to obtain sensitive data. Phishing is a type of cyberattack that takes place when a criminal sends an email that appears to be from a trustworthy source. A bank or company might use this technique to trick the receiver into divulging private information. Email spoofing is a similar attack. In this instance, the attacker sends an email that appears to be from someone other than the actual sender. especially by representing oneself as a trustworthy person, location, or object.

By publishing a DMARC record, you can protect your domain from these attacks. DMARC provides a way for domain owners to specify how email receivers should handle emails that fail SPF (Sender Policy Framework) and DKIM (Domain-Keys Identified Mail) checks. SPF and DKIM are email authentication protocols that help prevent email spoofing.

How do I publish a DMARC record?

To publish a DMARC record, you need to create a text file that contains the DMARC record. Then publish it in your domain’s DNS (Domain Name System) records. The DMARC record is a simple text file that contains instructions for email receivers about managing emails from your domain. 

Here is a basic DMARC record example:

v=DMARC1; p=reject;

This DMARC record specifies that the policy for handling failed SPF and DKIM checks is “reject”.

The DMARC record must be present in your domain’s DNS records in order for it to be published. You may do this using the website of your DNS service provider or domain registrar. The steps for adding a DMARC record to your DNS records may vary depending on your domain registrar or DNS provider.

Once you have published the DMARC record, it could take some time for it to travel over the Internet. Once the record has spread, you may use a DMARC record lookup tool to verify that your DMARC record generator is functioning properly.

“An ounce of prevention is worth a pound of cure.” 

Benjamin Franklin.
