Understanding DMARC Reports

DMARC helps protect your domain from email spoofing and phishing. One of its key features is DMARC reports, which show how your domain's emails are handled across the internet.

What Are DMARC Reports?​

DMARC reports are summaries sent by email providers (such as Microsoft and Google) that show which emails passed or failed SPF and DKIM authentication. These reports help domain owners identify unauthorized senders, misconfigurations, and potential security threats.

Types of DMARC Reports​

  1. Aggregate Reports (RUA) – Give a high-level view of email authentication results, showing the IP addresses sending email on your behalf and their SPF and DKIM status.
  2. Forensic Reports (RUF) – Provide detailed information about failed authentication attempts, including email headers and IP addresses. While helpful for identifying abuse, these reports may be limited by privacy regulations.

Why Are DMARC Reports Important?​

  • Detect Unauthorized Use: Identify attempts to send fraudulent emails using your domain.
  • Ensure Deliverability: Spot misconfigurations that may cause legitimate emails to be rejected.
  • Strengthen Security Policies: Use report insights to adjust SPF, DKIM, and DMARC policies for better protection.

How to Use DMARC Reports Effectively​

  1. Enable Reporting: Update your DMARC record to include an email address for receiving reports (rua= for aggregate reports and ruf= for forensic reports).
  2. Review Regularly: Analyze reports to detect patterns, unauthorized senders, or misconfigurations.
  3. Adjust Policies Gradually: Start with p=none to collect data, then move to p=quarantine or p=reject to block fraudulent emails.

Conclusion​

DMARC report analysis is crucial for maintaining email domain security. Regular review helps you detect unauthorized senders, improve email authentication, and strengthen overall security.

Rotate's Email Hub features comprehensive DMARC report analysis, simplifying the process of reviewing and acting on insights to keep your domain protected and compliant.

Frequently Asked Questions

Add-On
What is the Email Add-On?

The Email Add-On is a tool designed for Gmail and Outlook that helps you identify and manage malicious emails, including spam, phishing attempts, and malware. It enhances your email security by reporting suspicious emails and managing your personal spam list.

Mail Rules
Why are mail rules a security risk?

Mail rules can be exploited to exfiltrate data, hide security alerts, or modify incoming messages. Attackers often use forwarding rules to silently send emails to external accounts or create rules that auto-delete security notifications, making it harder to detect compromises.

Posture
Why is email security important?

Email is a common attack vector for phishing, spoofing, and other cyber threats. Properly configured DMARC, DKIM, and SPF records help prevent unauthorized parties from sending emails on behalf of your domain, protecting your organization from email-based attacks.

Scanning & Detection
What actions can I take on a malicious email?

When a malicious email is detected, you can take the following actions:

  • Block the email to remove it from the user’s inbox.
  • Release the email after it’s been blocked, putting it back in the inbox.
Can I deactivate Rotate Mail Scanning on a specific mailbox?

Yes, you can exclude specific mailboxes from Rotate Mail Scanning. This can be configured in the Configurations tab in the Email Hub under the Users and choose the users to exclude.

  • BEC (Business Email Compromise): A type of cybercrime where attackers impersonate company executives or employees to trick others into transferring money or sensitive information, often through email.
  • Malware: Malicious software designed to harm, exploit, or otherwise compromise the data or functionality of a computer, network, or device. Examples include viruses, trojans, and ransomware.
