About This Tool

The Email Spoof Test tool provides a safe, auditable way to model spoofed emails within a governed environment. It enables security teams to examine how mail authentication policies respond to attacker-like messages and to validate remediation steps. Conceptually, the tool builds a simulated message using defined sender and recipient fields, then performs domain-based checks (SPF, DKIM, DMARC) to assess alignment and potential delivery risk. It does not send real mail unless a sanctioned sandbox is configured; instead, it presents a realistic preview of headers and body content to the tester. This allows teams to identify misconfigurations, educate users, and quantify risk before incidents occur. Unique value lies in its explicit emphasis on consent, structured risk scoring, and exportable reporting that ties into incident response workflows. Use cases include phishing simulation campaigns, post-breach tabletop exercises, and compliance audits where understanding spoofing pathways is essential. Core features include multi-field input, DNS-based authentication analysis, an embeddable preview, a clear risk score, and actionable remediation guidance. The tool is designed for security operators, IT admins, red teams, and risk managers seeking repeatable, auditable spoofing assessments. It supports configurable thresholds and comprehensive reporting to assist governance and training programs.

How to Use

  1. Provide inputs: test_domain, from_email, to_email, subject, and message_body.
  2. Optionally enable header preview and attach simulated elements for realism.
  3. Run spoof test to compute SPF/DKIM/DMARC results and risk score.
  4. Review the email preview, headers, and diagnostic notes to identify misconfigurations.
  5. Export a test report and remediation guidance for incident response and policy updates.

Frequently Asked Questions

Find Quick Answers

What is this tool used for?
The tool is designed for authorized security testing to simulate spoofed emails, evaluate mail authentication (SPF, DKIM, DMARC), and strengthen defenses. It provides risk scoring and remediation guidance without delivering real messages to end users.
Does it send real emails?
No. The tool operates in a controlled, simulated mode. Real email delivery is avoided unless a sanctioned sandbox environment is explicitly configured and approved by policy. All results are test artifacts.
What inputs are required?
Required inputs include test_domain, from_email, to_email, subject, and message_body. Optional inputs may enable header previews or allow attachment simulation. All data should be provided only for authorized domains and recipients.
Is data handling compliant with privacy requirements?
Yes, provided the test is conducted with explicit consent and in line with applicable data protection rules. The tool logs testing activity locally, retains results per policy, and does not expose sensitive content beyond the scoped test data.
