DMARC Report Received from Bluehost: What You Need to Know
February 17, 2025 | 3 min read
Understanding DMARC Reports from Bluehost
Bluehost is a popular hosting and email service provider that allows users to manage their own domain emails. Ensuring proper email authentication for your Bluehost emails is essential for maintaining a strong sender reputation and protecting your domain from phishing or spoofing attacks. DMARC (Domain-based Message Authentication, Reporting & Conformance) reports from Bluehost provide detailed insights into how recipient servers handle your emails based on SPF and DKIM checks. By monitoring these reports, you can safeguard your domain and improve email deliverability.
Key Components of Bluehost DMARC Reports:
1. Source IP Address: Displays the IP address used by Bluehost to send your emails. Monitoring this helps you confirm that your emails are being sent from authorized Bluehost IP addresses, preventing unauthorized use of your domain.
2. DKIM Alignment Results : Indicates whether the DKIM signature in the email matches the domain in the “From” header. Bluehost supports DKIM signing, making proper DKIM alignment crucial for passing DMARC checks and ensuring email authentication.
3. SPF Alignment Results: Verifies whether the sending IP from Bluehost is authorized by your SPF record. Proper SPF alignment ensures that only authorized IP addresses are allowed to send emails on behalf of your domain.
4. Disposition: Tells you how the recipient server handled your emails—whether they were delivered, quarantined, or rejected—based on your DMARC policy settings.
5. Message Count: Displays the number of emails sent from a particular IP address, helping you monitor email volumes and identify any suspicious or unauthorized email activity.
Automating DMARC Parsing for Bluehost
Parsing DMARC XML reports manually for Bluehost, especially if you manage high email volumes, can be tedious and complex. Automating this process with tools like Skysnag makes it easier to monitor email security and take immediate action when needed.
– Data Aggregation Across Providers: If you use multiple email services along with Bluehost, Skysnag can aggregate DMARC reports from all email providers, giving you a unified view of your email authentication data across platforms.
– Visualizing Key Metrics: Skysnag transforms the raw DMARC XML data from Bluehost into visual dashboards that display important metrics such as DKIM/SPF pass rates, unauthorized email attempts, and top-sending IP addresses. This simplifies the management of your email authentication and security efforts.
– Automated Incident Response: Skysnag provides real-time alerts when emails sent through Bluehost fail DMARC checks, such as SPF or DKIM misalignment. This allows you to take prompt corrective action, such as updating DNS records or blocking suspicious IP addresses, to maintain proper email authentication.
– Forensic Reporting: DMARC reports often include detailed forensic data, such as full email headers from failed authentication attempts. For Bluehost users, this data can help diagnose why certain emails failed DKIM or SPF checks, allowing for more effective troubleshooting and security improvements.
Ensuring Proper DMARC Alignment for Bluehost
To ensure that your emails sent via Bluehost are properly authenticated, it’s important 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 ensures that your emails are delivered successfully while protecting your domain from misuse.
Skysnag’s Custom Solutions for Bluehost:
– DKIM Key Management: Skysnag ensures that the DKIM keys used for your Bluehost emails are properly aligned with your domain. If there are any misalignments or outdated DKIM keys, Skysnag will alert you, allowing you to fix the issue quickly and maintain compliance with DMARC policies.
– SPF Flattening: Using multiple services with Bluehost can lead to complex SPF records that may hit DNS lookup limits. Skysnag automates SPF flattening to optimize your SPF record, ensuring that it stays within DNS lookup limits and preventing any potential authentication failures.
– Policy Recommendations: Based on the insights gathered from your Bluehost DMARC reports, Skysnag can suggest changes to your DMARC policy, such as moving from “none” to stricter policies like “quarantine” or “reject.” This helps protect your domain from email spoofing and phishing while maintaining strong deliverability.
By automating DMARC parsing and providing tailored solutions for Bluehost users, Skysnag helps ensure your emails are properly authenticated, securely delivered, and protected from unauthorized use, maximizing both your domain’s reputation and email performance.
