DMARC Report Received from Symantec: What You Need to Know
February 19, 2025 | 3 min read
Understanding DMARC Reports from Symantec
Symantec, a leader in cybersecurity, offers advanced email security solutions that protect organizations from email-based threats such as phishing, spoofing, and malware. To ensure email authenticity and protect your domain from misuse, DMARC (Domain-based Message Authentication, Reporting & Conformance) is an essential tool. DMARC reports from Symantec provide key insights into how recipient servers handle your emails by evaluating SPF and DKIM checks. Monitoring and acting on these reports helps prevent email spoofing, safeguard your domain’s reputation, and improve email deliverability.
Key Components of Symantec DMARC Reports:
1. Source IP Address: Displays the IP address used by Symantec’s email security services to send your emails. Monitoring this ensures that your emails originate from authorized Symantec IP addresses, protecting your domain from unauthorized use.
2. DKIM Alignment Results: Indicates whether the DKIM signature in your emails aligns with the domain specified in the “From” header. Ensuring DKIM alignment is critical for passing DMARC checks and maintaining the integrity of your email authentication.
3. SPF Alignment Results: Verifies whether the sending IP address from Symantec is authorized by your SPF record to send emails on behalf of your domain. Proper SPF alignment helps prevent unauthorized IPs from sending emails using your domain, mitigating the risk of email spoofing.
4. Disposition: Provides information on how the recipient server handled your emails—whether they were delivered, quarantined, or rejected—based on your DMARC policy.
5. Message Count: Displays the number of emails sent from a specific IP, helping you track email volumes and detect any suspicious or unauthorized activity.
Automating DMARC Parsing for Symantec
Manually parsing DMARC XML reports from Symantec can be cumbersome, especially when managing large-scale email communications. Automating this process with tools like Skysnag simplifies the management of DMARC reports, helping you quickly identify and address email authentication issues.
– Data Aggregation Across Providers: If you use Symantec alongside other email providers, Skysnag can aggregate DMARC reports from multiple platforms into one unified view. This enables efficient monitoring and management of email authentication across all services.
– Visualizing Key Metrics: Skysnag transforms raw DMARC XML data from Symantec into visual dashboards, displaying critical metrics like DKIM/SPF pass rates, unauthorized email attempts, and top-sending IP addresses. This allows you to identify email authentication issues and take immediate action.
– Automated Incident Response: Skysnag provides real-time alerts when Symantec emails fail DMARC checks, such as SPF or DKIM misalignment. This allows you to take corrective action immediately, such as updating DNS settings or blocking suspicious IPs, ensuring your email authentication remains compliant.
– Forensic Reporting: Some DMARC reports offer forensic data, including full email headers from failed messages. For Symantec users, these detailed reports help diagnose why certain emails are not passing DMARC checks and provide insights to improve email security.
Ensuring Proper DMARC Alignment for Symantec
To ensure that emails sent through Symantec pass DMARC checks and are delivered successfully, it’s crucial that both DKIM and SPF are aligned with the domain specified in the “From” header. Misalignment can result in emails being quarantined or rejected by recipient servers, even if other checks pass. Proper DKIM and SPF alignment helps protect your domain from being misused for phishing and spoofing, improving email deliverability.
Skysnag’s Custom Solutions for Symantec:
– DKIM Key Management: Skysnag helps ensure that the DKIM keys used for Symantec-managed emails are correctly aligned and up-to-date. If any misalignments or outdated DKIM keys are detected, Skysnag will alert you, allowing you to resolve the issue quickly and maintain DMARC compliance.
– SPF Flattening: When using multiple services alongside Symantec, your SPF record can become complex and exceed DNS lookup limits. Skysnag automates SPF flattening, optimizing your SPF record to stay within DNS lookup limits, preventing authentication failures.
– Policy Recommendations: Based on patterns observed in your Symantec DMARC reports, Skysnag can recommend adjustments to your DMARC policy, such as moving from “none” to stricter enforcement modes like “quarantine” or “reject.” This enhances your domain’s protection against phishing and spoofing attacks while ensuring legitimate emails are delivered.
By automating DMARC report parsing and offering tailored solutions for Symantec users, tools like Skysnag ensure that your emails are properly authenticated, securely delivered, and protected from unauthorized use, all while enhancing your domain’s reputation and improving email performance.
