A properly configured DMARC (Domain-based Message Authentication, Reporting, and Conformance) record protects your domain against email spoofing and phishing attacks. However, having more than one DMARC record for your domain can cause serious issues with email delivery and reporting accuracy. This article will guide you through checking your DMARC configuration and resolving conflicts.
Why You Should Only Have One DMARC Record
Each domain is allowed to have only one DMARC record. If multiple records are detected, it can lead to inconsistent behavior from email servers. This can result in:
- Misclassification of legitimate emails as spam or rejection of emails entirely.
- Inaccurate DMARC reporting makes it difficult to analyze email threats or abuse.
- Potential conflicts that reduce your domain’s email deliverability and reputation.
How to Check Your DMARC Configuration
To verify your current DMARC setup, use our DMARC Lookup Tool. This tool will show you the existing DMARC record for your domain. If it detects more than one record, you'll need to address this to avoid conflicts.
Resolving Multiple DMARC Records
If our DMARC Lookup Tool indicates that your domain has multiple DMARC records, follow these steps to resolve the issue:
- Access your domain’s DNS settings.
- Remove any extra DMARC records, ensuring only one valid record remains.
Final Checks and Recommendations
- Regularly monitor your domain’s DMARC status to prevent accidental duplication.
- After updating your DNS settings, wait for changes to propagate and confirm your configuration using our tools.
- Ensuring a single DMARC record will help maintain strong email security and enhance your domain’s reputation.
By following these guidelines, you can prevent conflicts, protect your domain from abuse, and ensure consistent email deliverability.
