pip install dnspython checkdmarcpython scripts/agent.py --domain example.com --output email_security_report.json
Domain: example.com
SPF: v=spf1 include:_spf.google.com ~all (WARN: softfail allows spoofing)
DKIM: selector1 OK, selector2 OK
DMARC: v=DMARC1; p=none; rua=mailto:dmarc@example.com (WARN: policy=none, no enforcement)
Risk: HIGH - p=none with ~all allows email spoofing
