How to check smtp mail work or not in codeigniter

To check if SMTP mail works or not in CodeIgniter, you can use the email library provided by CodeIgniter. Here's an example of how you can do it:

First, make sure you have the email library loaded in your controller or model. You can do this by adding the following line of code:
```
$this->load->library('email');
```

Next, set the SMTP settings in the email library. You can do this by adding the following code:

$config = array(
 'protocol' => 'smtp',
 'smtp_host' => 'your_smtp_host',
 'smtp_user' => 'your_smtp_username',
 'smtp_pass' => 'your_smtp_password',
 'smtp_port' => 587,
 'mailtype' => 'text',
 'charset' => 'utf-8',
 'wordwrap' => TRUE
);
$this->email->initialize($config);

Replace your_smtp_host, your_smtp_username, your_smtp_password, and 587 with your actual SMTP settings.

Now, you can use the send_mail() method to send a test email. This method will return TRUE if the email is sent successfully, and FALSE otherwise.
```
$to = '[email protected]';
$subject = 'Test Email';
$message = 'This is a test email sent using CodeIgniter';
```

if ($this->email->send_mail($to, $subject, $message)) { echo 'Email sent successfully!'; } else { echo 'Error sending email!'; }

Replace `[email protected]` with the email address you want to send the test email to.

4. If the email is sent successfully, you can check the email logs to verify that the email was sent. You can do this by adding the following code:
```php
echo $this->email->print_debugger();

This will print the email logs to the screen, including the sender, recipient, subject, and message.

Here's the complete code:

<?php

class Test_email extends CI_Controller {

    public function index()
    {
        $this->load->library('email');

        $config = array(
            'protocol' => 'smtp',
            'smtp_host' => 'your_smtp_host',
            'smtp_user' => 'your_smtp_username',
            'smtp_pass' => 'your_smtp_password',
            'smtp_port' => 587,
            'mailtype' => 'text',
            'charset' => 'utf-8',
            'wordwrap' => TRUE
        );
        $this->email->initialize($config);

        $to = '[email protected]';
        $subject = 'Test Email';
        $message = 'This is a test email sent using CodeIgniter';

        if ($this->email->send_mail($to, $subject, $message)) {
            echo 'Email sent successfully!';
        } else {
            echo 'Error sending email!';
        }

        echo $this->email->print_debugger();
    }

}

?>

Note that you should replace your_smtp_host, your_smtp_username, your_smtp_password, and 587 with your actual SMTP settings.
