Email Domain Security (SPF/DKIM/DMARC)
Email authentication protocols prevent attackers from sending spoofed emails that appear to come from your domain.
Why It Matters
Without SPF, DKIM, and DMARC, attackers can send phishing emails impersonating your domain. This damages your reputation and enables fraud.
How We Check
We query DNS for SPF, DKIM, and DMARC records and verify proper configuration including policy strictness.
How to Fix
Set up SPF to list authorized mail servers. Configure DKIM signing. Add DMARC with p=quarantine or p=reject policy. Start with p=none for monitoring.
