## CLI Commands

```bash

rnoe-mail.py list

# List with options
rnoe-mail.py list --limit 10 --days 7 --account myaccount

# Read email (scanned for prompt injection!)
rnoe-mail.py read <uid>

# Send email (requires send permission)
rnoe-mail.py send --to "user@example.com" --subject "Hello" --body "Message"

# List folders
rnoe-mail.py folders

# Move email to folder
rnoe-mail.py move <uid> --to "Archive"
```

## Prompt Injection Detection

All emails are automatically scanned:

- **Safe**: Content displayed normally
- **Injection detected**: Exit code 2, shows score + patterns

Uses ProtectAI's DeBERTa model (local inference, no external APIs).

## Permissions

| Permission | Description | Default |
|------------|-------------|---------|
| `read` | List and read emails | `true` |
| `send` | Send emails via SMTP | `false` |
| `delete` | Delete emails | `false` |
| `move` | Move emails between folders | `false` |

## Security Notes

- Emails are scanned for prompt injection before content is returned
- ML model runs locally — no data sent to external APIs
- Enable write permissions only when needed
- Consider using app-specific passwords
