🎭 Email Spoof Checker

Analyze SPF and DMARC records to determine the risk of email spoofing.

ℹ️ About Email Spoof Checker

The Email Spoof Checker is a high-level security auditing tool designed to assess how vulnerable a domain is to impersonation. 'Spoofing' occurs when an attacker sends an email that appears to come from a legitimate domain, often used in phishing and Business Email Compromise (BEC) attacks.

This tool analyzes the domain's SPF and DMARC configurations to determine a 'Risk Level.' A domain with no authentication records is considered 'High Risk,' as anyone on the internet can send mail using that domain name. By implementing SPF and a strong DMARC policy (like p=reject), you can reduce this risk to 'Low,' ensuring that unauthorized mail is blocked before it reaches users' inboxes.

📖 How to use Email Spoof Checker

1. Enter the domain name you wish to test.
2. Click 'Run Tool' to perform the security analysis.
3. Review the 'Spoof Risk' level.
4. Use the results to identify missing security layers and strengthen your email defense.

❓ Frequently Asked Questions

What is 'Email Spoofing'?

Spoofing is the creation of email messages with a forged sender address. The goal is to trick the recipient into thinking the email is from a trusted source.

Why do I need both SPF and DMARC?

SPF only authorizes servers. DMARC ensures that the 'From' address the user sees matches the authorized SPF/DKIM domains. You need both for complete protection.
