Cloudflare's DMARC reporting provides detailed information about authentication failures. Analyze the aggregate reports to identify which sending sources are failing SPF or DKIM checks. Investigate the reasons for these failures (e.g., incorrect SPF records, invalid DKIM signatures) and correct them to improve your DMARC compliance.
