Understanding DMARC Reports from 1&1 IONOS
1&1 IONOS is a well-known web hosting and email service provider that offers a wide range of solutions for businesses, including email hosting, domain registration, and web security services. To ensure the emails you send from 1&1 IONOS are properly authenticated, DMARC (Domain-based Message Authentication, Reporting & Conformance) reports are crucial. These reports provide insights into how recipient servers handle your emails, especially focusing on SPF and DKIM alignment. Monitoring and acting on these reports helps protect your domain from phishing and spoofing while improving email deliverability.
Key Components of 1&1 IONOS DMARC Reports:
1. Source IP Address: Displays the IP address from which 1&1 IONOS email services send your emails. Monitoring this ensures that your emails originate from authorized IONOS IP addresses, protecting your domain from unauthorized use.
2. DKIM Alignment Results: Verifies whether the DKIM signature in your emails matches the domain specified in the “From” header. Ensuring DKIM alignment is crucial for passing DMARC checks and maintaining the trustworthiness of emails sent from 1&1 IONOS.
3. SPF Alignment Results: Confirms whether the sending IP address from 1&1 IONOS 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, protecting it from email spoofing.
4. Disposition: Informs you of 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 particular IP, helping you monitor email volumes and detect any suspicious or unauthorized activity from your domain.

– Forensic Reporting: Some DMARC reports offer forensic data, such as full email headers from failed messages. For 1&1 IONOS users, this level of detail is invaluable for diagnosing why certain emails failed authentication checks and for improving email security.
Ensuring Proper DMARC Alignment for 1&1 IONOS
To ensure that emails sent from 1&1 IONOS pass DMARC checks and are delivered successfully, both DKIM and SPF must align with the domain used in the “From” header. Misalignment can cause emails to be quarantined or rejected by recipient servers, even if they pass other checks. Proper DKIM and SPF alignment helps protect your domain from being spoofed and improves email deliverability.
