## 描述

InboxProof is a missed lead detection layer for WordPress forms.

SMTP plugins help WordPress send emails. InboxProof protects the leads when those
emails fail.

The plugin captures supported form submissions, saves a safe copy in the WordPress
admin, traces the outgoing notification email, and flags leads that may be at risk
because no notification was created or WordPress reported an email failure.

InboxProof is not an SMTP plugin and does not replace WP Mail SMTP, FluentSMTP, 
Post SMTP, Easy WP SMTP, Mailgun, SendGrid, Brevo, Amazon SES, Gmail SMTP, or similar
tools. It is designed to work alongside them.

### Free Features

 * Contact Form 7 submission capture.
 * WPForms Lite submission capture.
 * Lead Safe Inbox in wp-admin.
 * Basic email logging through wp_mail hooks.
 * Form-to-email trace matching.
 * Probable matching when trace context is unavailable.
 * Missing notification detection.
 * Delayed missing-notification checks to reduce false positives.
 * wp_mail success/failure status.
 * Manual resend from the original email log or saved lead fallback.
 * Basic SPF, DKIM, and DMARC checks.
 * From-domain mismatch warning.
 * Basic plugin detection.
 * Dashboard widget.
 * Search, filters, pagination, and bulk lead status actions.
 * Privacy masking for likely sensitive fields.
 * Configurable retention controls for saved leads, email logs, and history.

### Privacy

InboxProof stores supported form submissions, related email log data, diagnostic
results, and trace events in your WordPress database.

InboxProof can store email bodies to support resend/recovery. You can turn off email
body storage in the plugin settings.

InboxProof can mask likely sensitive form fields, such as passwords, tokens, and
card-like fields. This masking setting is enabled by default.

### External Services

The free version of InboxProof does not send captured leads, email logs, diagnostic
results, or plugin settings to any external service.

### Support

For InboxProof support, email support@tazrinhossain.com.

If you installed InboxProof from WordPress.org, you can also use the plugin support
forum.

## 常见问题

### Is InboxProof an SMTP plugin?

No. InboxProof does not configure SMTP or replace your existing mail provider. It
monitors form leads and WordPress email attempts so you can see whether a lead was
protected.

### Does InboxProof store form submissions?

Yes. InboxProof stores supported form submissions in a custom database table so 
admins can recover leads when notification emails fail or are missing.

### What does “notification_missing” mean?

It means a supported form submission was captured, and no matching WordPress email
was found after InboxProof’s delayed check ran.

### What does “email_failed” mean?

It means WordPress attempted to send a notification email and fired the `wp_mail_failed`
hook.

### Does InboxProof send my leads to an external service?

No. Lead capture, email logs, and diagnostics are stored locally in your WordPress
database.
