Usage Examples

"audit example.com"
"check DNS for cloudflare.com"
"is patrikx3.com secure?"
"whois google.com"
"check email deliverability for example.com"
"test email support@example.com"

Email Test Flow

The email_test tool performs a live end-to-end email deliverability test:

Call email_test with an email address (e.g. support@example.com) and optional language code
The system sends a test email to that address
The recipient replies to the test email
Results are automatically sent by email — no polling required! The result email includes:
- Score (0-10)
- SPF, DKIM, DMARC authentication results
- Individual blacklist status for all 23 checked lists
- Spam score
- Message format and header analysis
- AI-powered recommendations in the selected language
Optionally, call email_test_result with the returned testId to get results programmatically

Supported languages: en, hu, de, fr, es, it, cs, ru, zh, ja

This goes beyond passive DNS checks (email_deliverability) by verifying that email authentication actually works in practice on a real delivered message.

Configuration

Environment Variable	Default	Description
`P3X_NETWORK_URL`	`https://network.corifeus.com`	Base URL for the network API
