As the world becomes increasingly connected, it's more vital than ever to have a strong cybersecurity infrastructure in place. Email has long been a popular target for cybercriminals, making the setup of DMARC an essential part of any online security effort. In this comprehensive guide, we'll dive into setting up DMARC to help protect your business from voice phishing and other cyber threats.
What is DMARC?
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that provides a robust method to fight phishing and spoofing by validating the authenticity of the sender's domain. By setting up DMARC, you create an extra layer of security for your email system, making it a powerful tool in your cybersecurity toolbox.

There are several reasons why setting up DMARC is essential for every business:
- Improved email deliverability: DMARC reduces the chances of your emails ending up in the spam folder by verifying sender authenticity.
- Fights phishing and spoofing: DMARC makes it easier for receivers to identify legitimate emails, reducing the risk of falling victim to phishing and spoofing attacks.
- Enhanced reputation: By using DMARC, you demonstrate to your customers and partners that you prioritize security and value their privacy.
- Visibility of email ecosystem: DMARC reports provide valuable insights into your email channels, enabling you to identify potential issues or unauthorized senders.
How to Set Up DMARC
Setting up DMARC involves creating a DMARC policy and applying it to your domain's DNS records. Follow these steps to set up DMARC:
- Analyze your domain's email sources to identify all authorized senders. Make a list of all third-party services, transactional email providers, and other applications you use to send emails.
- Verify that all your authorized senders are using SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) authentication methods. Both SPF and DKIM are essential components of DMARC; therefore, ensure they are correctly implemented for each sender.
- Create your DMARC policy based on your organization's needs. You can choose from three policies: none, quarantine, or reject. We recommend starting with the "none" policy during the initial setup as you monitor report data and tweak policies accordingly.
- Add the DMARC policy to your domain's DNS records in the form of a TXT record. This record should include the DMARC tag 'v=DMARC1', your chosen policy ('p=none', 'p=quarantine', or 'p=reject'), and an email address where you wish to receive DMARC reports ('rua=mailto:reports@example.com').
- Monitor DMARC reports to identify any unauthorized senders or potential issues. Make necessary adjustments to your SPF and DKIM records if needed.
- Once you're confident in your DMARC setup, consider increasing the policy level to "quarantine" or "reject" to enforce stricter security measures against phishing and spoofing.
Setup DMARC Example:
Imagine you own a small e-commerce business called MyShop. You've noticed an increase in phishing attacks targeting your customers, and you want to set up DMARC to strengthen your email security. You use MailChimp to send promotional emails and Gmail for your internal communications.
First, verify that MailChimp and Gmail have SPF and DKIM authentication enabled. Next, create a DMARC policy with the "none" level for monitoring purposes. Your DMARC record in your DNS records would look like this:
v=DMARC1; p=none; rua=mailto:reports@myshop.com
After monitoring reports and making adjustments, you're confident in your DMARC setup. You increase your policy level to "quarantine" to ensure potential phishing emails get flagged before reaching your customers:
v=DMARC1; p=quarantine; rua=mailto:reports@myshop.com
In conclusion, setting up DMARC is a crucial step in securing your email infrastructure against cyber threats like voice phishing. By following this guide, you'll be better prepared to protect your business from phishing attempts and improve your overall email deliverability.
