DMARC Deployment Best Practices
Implementing DMARC requires a strategic approach to avoid blocking legitimate emails. Start with a monitoring-only policy (p=none) to understand your email ecosystem. Analyze aggregate reports for 2-4 weeks to identify all legitimate sending sources. Once confident, gradually move to quarantine and then reject policies, using percentage to control the rollout speed.
Understanding DMARC Alignment
DMARC alignment determines how strictly SPF and DKIM domains must match the From domain. Relaxed alignment allows organizational domain matches (subdomain.example.com passes for example.com), while strict alignment requires exact matches. Start with relaxed alignment unless you have specific security requirements, as strict alignment can cause legitimate emails to fail DMARC checks.
DMARC Reporting Explained
- Aggregate Reports (RUA): Daily XML reports showing authentication results statistics
- Forensic Reports (RUF): Real-time reports for individual message failures (privacy limited)
- Report Analysis: Use reports to identify unauthorized senders and missing configurations
- Third-party Services: Consider using DMARC report analyzers for easier interpretation
