### Test Files

1. **Simple Test Script:** `/public/test-email-simple.php`
   - Access: `http://localhost/test-email-simple.php`
   - Tests: Config, database, SMTP settings, PHPMailer, connection, and sends test email
   - Shows detailed SMTP debug output

2. **Settings Page Test:** `/settings/email`
   - Access: `http://localhost/settings/email`
   - Click "Test Connection" button to verify SMTP connectivity
   - Shows real-time success/failure feedback

## Email System Features

### 1. EmailService (`services/EmailService.php`)

Centralized service for sending all system emails using PHPMailer.

**Available Methods:**
```php
// Authentication & Security
$emailService->sendOTP($email, $name, $otpCode, $expiryMinutes);
$emailService->sendPasswordReset($email, $name, $resetToken, $expiryMinutes);
$emailService->sendBackupCodes($email, $name, $backupCodes);
$emailService->sendUserInvitation($email, $name, $invitationToken);

// Business Documents
$emailService->sendQuoteForApproval($email, $recipientName, $quoteNumber, $quoteLink, $totalAmount, $senderName, $expiryDate);
$emailService->sendNDAForSignature($email, $recipientName, $ndaNumber, $ndaLink, $opportunityName, $senderName, $expiryDate);
$emailService->sendFullyExecutedNDA($email, $recipientName, $ndaNumber, $ndaLink, $opportunityName, $senderName);
```

### 2. Email Templates

All emails use professional HTML templates with:
- Company branding (logo, name, contact info from system settings)
- Responsive design
- Consistent header/footer styling
- Clear call-to-action buttons
- Plain-text alternative for compatibility

### 3. Valid Mailboxes (Mail Server)

Based on testing, these email addresses exist on the mail server:
- `erp_system@mavrix.one` - System sender account
- `rick@mavrix.one` - User account (tested successfully)
- `info@mavrix.one` - General company email

**Note:** Email addresses in the ERP database (admin@mavrix.one, brian@mavrix.one, etc.) may not exist as actual mailboxes on the mail server. Emails sent to non-existent addresses will fail with "User unknown in virtual mailbox table" error.

## Settings Page Updates

   - ✅ Success badge (green) with checkmark
   - ✅ Error badge (red) with detailed error message
   - ✅ Auto-hide success message after 5 seconds
   - ✅ No page reload required (AJAX)

3. **Better User Experience**

   - ✅ Professional error messages
   - ✅ Bootstrap 5 styling for consistency

## Usage Examples

### Send Password Reset Email

```php
require_once BASE_PATH . '/services/EmailService.php';

$emailService = new EmailService();
$resetToken = bin2hex(random_bytes(32));

$result = $emailService->sendPasswordReset(
    'user@example.com',
    'John Doe',
    $resetToken,
    30 // expires in 30 minutes
);

if ($result) {
    echo "Password reset email sent!";
} else {
    echo "Failed to send email";
}
```

### Send OTP for MFA

```php
$otpCode = sprintf('%06d', mt_rand(0, 999999));

$result = $emailService->sendOTP(
    'user@example.com',
    'Jane Smith',
    $otpCode,
    5 // expires in 5 minutes
);
```

### Send Quote for Approval

```php
$result = $emailService->sendQuoteForApproval(
    'customer@company.com',
    'Bob Customer',
    'Q-2026-001',
    'https://erp.mavrix.one/quotes/sign/abc123token',
    15000.00,
    'Sales Rep Name',
    '2026-02-28' // optional expiry date
);
```

## Troubleshooting

### Email Not Sending

1. **Check SMTP Settings:**
   ```bash
   mysql -u rpmbbu -p'z8468RPMerkuri123!' brickwal_m1_ds -e \
   "SELECT setting_key, setting_value FROM system_settings WHERE setting_key LIKE 'smtp%'"
   ```

2. **Test Connectivity:**
   ```bash
   nc -zv 172.16.4.250 587
   ```
   Should return: `Connection to ************ port 587 [tcp/submission] succeeded!`

3. **Run Test Script:**
   ```bash
   php /Users/mavrixone/LocalPHPStorm/m1_erp_web/public/test-email-simple.php
   ```

4. **Check PHP Error Logs:**
   Look for PHPMailer errors in error_log

### Recipient Not Receiving Email

1. **Verify mailbox exists** on mail server (172.16.4.250)
2. **Check spam/junk folders**
3. **Verify email address** is correct
4. **Test with known working address** (rick@mavrix.one)

### Connection Timeout

1. **Firewall blocking?** Check if port 587 is open
2. **Wrong server?** Verify 172.16.4.250 is correct
3. **Network issue?** Ping the server

## Network Configuration

### Mail Server Details
- **Hostname:** mail.mavrix.one
- **Internal IP:** 172.16.4.250
- **External IP:** 172.99.62.118
- **Software:** Postfix (ESMTP Postcow)
- **Accessible From:** Internal network (172.16.x.x)

### Development Machine
- **Public IP:** 68.4.46.238
- **Access:** Can reach internal mail server (172.16.4.250)
- **Port 587:** ✅ Open and accessible

### Firewall Notes
- External IP (172.99.62.118) has firewall blocking SMTP ports from external IPs
- Internal IP (172.16.4.250) allows connections from internal network
- Development machines must use internal IP for SMTP

## Security Considerations

1. **Password Storage:** SMTP password stored in database (encrypted in production recommended)
2. **TLS Encryption:** All SMTP connections use STARTTLS encryption
3. **SSL Verification:** Disabled for development (self-signed cert OK)
4. **Authentication:** Required for all outgoing emails
5. **Rate Limiting:** Consider adding rate limits for email sending (future enhancement)

## Future Enhancements

Optional improvements for consideration:

- [ ] Email queue system for bulk sending
- [ ] Email sending logs/audit trail
- [ ] Retry logic for failed emails
- [ ] Email templates in database (currently in code)
- [ ] Multi-language email support
- [ ] Email scheduling
- [ ] Email tracking (open/click tracking)
- [ ] Attachment support in EmailService
- [ ] BCC to admin for important emails
- [ ] Email whitelist/blacklist
