You'll start receiving DMARC reports within 24-48 hours after publishing your DMARC record. However, it can take up to 7 days to get comprehensive data from all major email providers.
First, check your SPF and DKIM configuration. Most legitimate email blocking occurs due to authentication failures. You can temporarily set your DMARC policy to 'p=none' while investigating, then gradually increase enforcement.
Include all authorized third-party services in your SPF record using 'include:' mechanisms. For DKIM, ask your service providers to sign emails with your domain's DKIM key, or set up DKIM delegation.
'Quarantine' moves suspicious emails to spam/junk folders, allowing users to review them. 'Reject' instructs receiving servers to completely block the emails. Start with quarantine before moving to reject.
Initially, review reports daily for the first week, then weekly for a month. Once stable, monthly reviews are sufficient unless you receive threat alerts or make infrastructure changes.
Yes, but positively! Properly configured DMARC improves deliverability by building trust with receiving servers. However, misconfigured DMARC can block legitimate emails, so test thoroughly before enforcing strict policies.
SPF records are limited to 10 DNS lookups. Flatten your SPF record by replacing 'include:' mechanisms with direct IP addresses, or use SPF flattening services.
Check that your DKIM keys match between your email service and DNS records. Ensure the DKIM record hasn't been truncated in DNS and that the selector is correct.
Verify that your 'From:' domain matches your SPF/DKIM domains. For relaxed alignment, subdomains are allowed. For strict alignment, domains must match exactly.
Confirm your DMARC record is published correctly at '_dmarc.yourdomain.com'. Check that your RUA email address is valid and can receive reports. Some providers may take 24-72 hours to start sending reports.
Forensic reports can be overwhelming. Consider removing the 'ruf=' tag temporarily while investigating issues, or filter reports to specific failure types using the 'fo=' tag.
