DMARC IS A CRITICAL AND CRUCIAL PART OF EMAIL SECURITY.
CYBERSECURITY IS A TOP PRIORITY AND THE NEW NORM.
Director of IT, David Gawler says.
A typical DMARC record contains at least three important components (or tag-value pairs). Consider this sample DMARC record:
all Email Experts need to add DMARC records at the domain name registrar level and local name server record position. For Linux web hosting that’s Bind and typically WHM for cPanel web hosting users or DNS Manager in Windows Server if you are on Microsfot. Adding a complex TXT record for DNS makes you DMARC email secure and email compliant.

**What is DMARC in Layman’s Terms? A Guide to Understanding Email Security**
In today’s digital age, email has become a crucial means of communication for individuals and businesses alike. However, with the rise of cyber threats and email-based attacks, ensuring the security and authenticity of email communications has become a top priority. This is where DMARC comes into play. DMARC, which stands for Domain-based Message Authentication, Reporting, and Conformance, is a powerful email security protocol designed to protect against email phishing and spoofing. In this article, we will explain what DMARC is in simple terms and how it helps ensure the safety of your email communications.
**Understanding the Basics of DMARC**
Imagine you want to send a letter through the postal service. You write the letter, put it in an envelope, and write your address as the sender. Now, you entrust the letter to the postal service, hoping it will reach its intended recipient without any tampering or interception along the way. In a similar fashion, email operates on a system that includes a sender (you), a recipient (the person you’re emailing), and an intermediary system (the email service providers and servers).
The problem arises when cybercriminals attempt to impersonate the sender, posing as someone they’re not, just like someone trying to forge your handwriting on a letter. This is where DMARC steps in to protect the authenticity of emails and verify the legitimacy of the sender’s domain.
**DMARC – The Email Security Superhero**
DMARC acts as an email security superhero, protecting your inbox from deceitful emails. It operates by using two existing email authentication technologies: SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).
1. **SPF (Sender Policy Framework):** SPF is like a whitelist that specifies the authorized email servers allowed to send emails on behalf of your domain. It’s as if you have a list of trusted messengers who can deliver your letters. When an email is received, the recipient’s email server checks if the sending server is on your SPF list. If it’s not, the email is flagged as suspicious.
2. **DKIM (DomainKeys Identified Mail):** DKIM is like adding a digital signature to your letter. When you send an email, your email server signs the email with a unique key specific to your domain. The recipient’s server can then verify this signature using the public key in your domain’s DNS records. If the signature is valid, it proves that the email is indeed from you and hasn’t been tampered with.
**The Role of DMARC – Keeping the Bad Guys Out**
Now, imagine a scenario where you’ve employed both SPF and DKIM. DMARC acts as the security guard checking both SPF and DKIM to ensure everything aligns and validates. It’s like adding an additional layer of security to verify that the authorized sender (you) is indeed the one sending the email.
Here’s how DMARC works:
1. **Receiving an Email:** When someone sends you an email, their email server will have information about SPF and DKIM in the email’s headers.
2. **DMARC Policy Check:** Your email service provider will then check if the email’s sender domain has a DMARC policy in place. If it does, DMARC takes action accordingly.
a. If SPF and DKIM alignment checks pass (meaning everything is in order and the email is legitimate), DMARC lets the email through to your inbox.
b. If SPF or DKIM alignment fails (meaning the email doesn’t align with the authorized sender’s domain), DMARC can take actions like quarantining the email to a spam folder or rejecting it altogether.
3. **Reporting and Monitoring:** DMARC provides feedback and reports on email authentication results. These reports help you understand how your domain is being used and any attempts of spoofing or phishing.
**The Advantages of DMARC – Staying Safe and Informed**
The primary advantage of DMARC is that it helps protect you and your recipients from falling victim to email spoofing and phishing attacks. By validating the authenticity of email senders, DMARC ensures that only legitimate emails reach your inbox. Here are some key benefits:
1. **Email Protection:** DMARC significantly reduces the risk of receiving fraudulent emails, safeguarding you from phishing attempts and malicious activities.
2. **Brand Reputation:** Implementing DMARC helps protect your brand’s reputation, as cybercriminals won’t be able to impersonate your domain and deceive your customers or contacts.
3. **Email Deliverability:** As DMARC ensures the legitimacy of your emails, it improves your email deliverability rates. This means your emails are less likely to end up in spam folders.
4. **Visibility and Insights:** DMARC generates reports that provide valuable insights into your email ecosystem. You can monitor email sending practices, identify unauthorized sources, and take corrective actions.
5. **Encouraging DMARC Adoption:** Implementing DMARC can positively impact your email communication with large email service providers like Gmail, Yahoo, and Microsoft, as they often favor emails from domains with strong DMARC policies.
**Considerations and Implementation**
While DMARC is a powerful email security tool, implementing it requires careful consideration and proper configuration. Here are some key points to keep in mind:
1. **Gradual Implementation:** DMARC implementation can be done gradually, starting with monitoring mode (p=none) to understand how emails from your domain are being used. This allows you to make necessary adjustments before moving to enforcement mode.
2. **DNS Records Management:** DMARC policies are implemented through DNS records for your domain. It’s essential to manage these records correctly and keep them up to date.
3. **Collaboration with IT Teams:** DMARC implementation might require collaboration with your organization’s IT or technical teams to configure email servers and interpret reports.
4. **Third-Party Services:** If you use third-party email services for marketing or communication, you must ensure they are aligned with your DMARC policy to prevent legitimate emails from being blocked.
DMARC is a critical email security protocol that plays a vital role in safeguarding your inbox from malicious emails and phishing attacks. By working alongside SPF and DKIM, DMARC ensures the legitimacy of the email sender, helping you stay safe and informed in the digital realm.
While implementing DMARC requires careful planning and configuration, the benefits are significant. By protecting your brand reputation, improving email deliverability, and gaining valuable insights, DMARC empowers you to take control of your email communication and enhance your overall online security.
