Domain Email Health Checker
Comprehensive analysis of your domain's email security posture including SPF, DMARC, and DKIM configuration with detailed recommendations for improvement.
Understanding Email Security Records
SPF (Sender Policy Framework)
Specifies which mail servers are authorized to send email on behalf of your domain, preventing email spoofing.
DMARC (Domain-based Message Authentication)
Tells receiving servers what to do with emails that fail SPF or DKIM checks, providing policy enforcement.
DKIM (DomainKeys Identified Mail)
Uses cryptographic signatures to verify that emails haven't been tampered with during transit.

Important Notes
Scope of Analysis
This tool provides a basic security assessment based on DNS record presence and configuration. It does not perform deep validation like SPF lookup limits, full DKIM signature verification, or real-time email testing.
DKIM Limitations
DKIM analysis attempts auto-detection with common selectors if none is provided. However, many email providers use unique or multiple selectors. For precise results, check your sent email headers or contact your email provider to find the correct selector.
