Understanding DMARC Reports from Zoho Mail
Zoho Mail is a widely used business email platform that emphasizes security and privacy. To maintain email security and domain reputation, it’s important to monitor how your emails are being authenticated. DMARC (Domain-based Message Authentication, Reporting & Conformance) reports from Zoho Mail provide insight into how recipient servers handle your emails, specifically focusing on SPF and DKIM alignment. This helps ensure that your emails are properly authenticated and protected from potential spoofing or phishing attacks.
Key Components of Zoho Mail DMARC Reports:
1. Source IP Address: This field identifies the IP address from which Zoho Mail sent your email. It helps verify whether the email originated from a legitimate Zoho Mail IP or an unauthorized source.
2. DKIM Alignment Results: This shows if the DKIM signature in the email aligns with the domain in the “From” header. Zoho Mail allows for easy DKIM signing configuration, and it’s critical to ensure proper alignment for passing DMARC checks.
3. SPF Alignment Results: Ensures that the sending IP from Zoho Mail is authorized by your domain’s SPF record to send emails. This is a key check to prevent unauthorized use of your domain.
4. Disposition: Indicates how the recipient server treated the email—whether it was delivered, quarantined, or rejected—based on the DMARC policy you’ve defined for your domain.
5. Message Count: Displays the number of emails that matched specific criteria, sent from a particular IP. This helps track email campaigns or detect any suspicious activity.

Ensuring Proper DMARC Alignment for Zoho Mail
To maximize the effectiveness of DMARC, it’s crucial that both DKIM and SPF align with the domain used in the “From” header of your emails. Misalignment can cause emails to be quarantined or rejected, even if they pass other checks. Zoho Mail allows for simple configuration of DKIM and SPF, but consistent monitoring through DMARC reports is essential for maintaining proper alignment and strong email deliverability.
