AntiEmailSpoof checks two essential email security protocols:

- DMARC (Domain-based Message Authentication, Reporting & Conformance): Tells receiving mail servers how to handle unauthorized emails
The tool provides different status levels based on your domain's configuration:
- ✅ Secure: Domain has both SPF and DMARC with reject policy
- 🔸 Moderate: Domain has basic protection but uses quarantine policy
⚠️ Warning: Domain has partial or basic configuration- ❌ Vulnerable: Domain lacks proper email security measures
- Uses Google's DNS-over-HTTPS API
- Runs entirely in the browser
