Why DMARC is important for email security
Email spoofing is a common cyberthreat that can lead to disastrous consequences for your business. To prevent this, implementing email authentication policies like DMARC (Domain-based Message Authentication, Reporting, and Conformance) is essential to protect your domain from phishing attacks.

DMARC combines two existing email authentication standards, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), with applied policies. By using DMARC, you can set rules for receiving mail servers in terms of how to handle emails that might appear to come from your domain, but are actually unauthorized or fraudulent.
Implementing DMARC provides you with the following advantages:
- Protection against email spoofing and phishing attacks
- Easier troubleshooting of email delivery issues
- Increase in trust and credibility for your domain
- Insight into your domain's email ecosystem, including authorized and unauthorized senders
Understanding and creating DMARC records
DMARC records are DNS (Domain Name System) TXT (Text) records inserted within your domain's DNS settings. They contain specific tags and their values, which enable email servers to validate and apply policies to incoming emails.
Here's a general structure of a DMARC record:
dmarc.example.com IN TXT "v=DMARC1; p=none; rua=mailto:reports@example.com;"
- v: The DMARC version (DMARC1).
- p: The policy to apply, which can be:
- none: do nothing special, just monitor emails.
- quarantine: mark emails as suspicious, move them to spam folder or similar.
- reject: reject the email entirely.
- rua: The email address to receive aggregate reports on email verification.
Additional optional tags can be included depending on your needs, such as percent of emails to apply the policy on, alignment mode for SPF and DKIM, or individual failure reporting.
Using a DMARC record checker
To ensure that your DMARC record is formatted correctly, a DMARC record checker tool is essential. These tools analyze your DMARC record's syntax and provide feedback on any errors or improvements required.
Here are some trusted online DMARC record checker tools:
- MxToolBox (https://mxtoolbox.com/DMARC.aspx)
- DMARC Analyzer (https://www.dmarcanalyzer.com/dmarc/dmarc-record-check/)
- Agari (https://agari.com/project-dmarc/check-dmarc-record/)
While using a DMARC record checker, always provide your domain name and select DMARC as the type of record you want to verify.
DMARC Record Checker Example:
In a practical scenario for an online retail business, its domain "examplestore.com" should set up a DMARC record to protect its customers from receiving illegitimate emails that may seem to be from the store.
1. First, create a DMARC record using the appropriate tags, and insert it into the domain's DNS settings:
dmarc.examplestore.com IN TXT "v=DMARC1; p=reject; rua=mailto:dmarc-reports@examplestore.com; adkim=r; aspf=r;"
2. Use one of the recommended DMARC record checker tools to verify that the syntax and values are correct.
3. Monitor and analyze the aggregate reports sent to the specified email address and ensure that the DMARC implementation is working correctly.
Improving your email security should be a top priority, and DMARC records act as a powerful shield against many cyberthreats.
