Understanding DMARC Reports from Tutanota
Tutanota is a privacy-focused, secure email provider known for its end-to-end encryption and commitment to user privacy. Ensuring that emails sent through your Tutanota-hosted domain are properly authenticated and protected from phishing, spoofing, and unauthorized use is crucial. DMARC (Domain-based Message Authentication, Reporting & Conformance) reports from Tutanota offer key insights into how recipient servers handle your emails, specifically by analyzing SPF and DKIM alignment. Monitoring these reports helps secure your domain and improve email deliverability, ensuring that your messages are delivered to the intended recipients.
Key Components of Tutanota DMARC Reports:
1. Source IP Address: Displays the IP address from which Tutanota’s servers send your emails. Monitoring this ensures that your emails are being sent from Tutanota-authorized IP addresses, helping protect your domain from spoofing or unauthorized email activity.
2. DKIM Alignment Results: Indicates whether the DKIM signature in your emails aligns with the domain specified in the “From” header. Proper DKIM alignment is crucial for passing DMARC checks and verifying the authenticity of emails sent through Tutanota.
3. SPF Alignment Results: Verifies whether the sending IP address from Tutanota is authorized by your domain’s SPF record. Ensuring SPF alignment protects your domain from unauthorized use, preventing email spoofing and malicious email attempts.
4. Disposition: Provides information on how the recipient server treated your emails—whether they were delivered, quarantined, or rejected—based on the DMARC policy you have configured.
5. Message Count: Displays the number of emails sent from a particular IP address, helping you track email activity and detect any unusual or unauthorized behavior linked to your domain.

Ensuring Proper DMARC Alignment for Tutanota
For emails sent through Tutanota to pass DMARC checks and be successfully delivered, both DKIM and SPF must align with the domain specified in the “From” header. Misalignment can cause emails to be quarantined or rejected by recipient servers. Ensuring proper DKIM and SPF alignment protects your domain from spoofing and phishing while improving email deliverability.
