regarding mail sent from my custom registration form in drupal - php

Question

I have created a custom registration form in Drupal 8, and now i want to sent a mail from the submission of the form. So I have did it like this
This is my .module file
/**
* Implements hook_mail().
*/
function Registration_form_mail($key, &$message, $params) {
$options = array(
'langcode' => $message['langcode'],
);
switch ($key) {
case 'contact_form':
$message['from'] = \Drupal::config('system.site')->get('mail');
$message['subject'] = $params['subject'];
$message['body'][] = $params['body'];
break;
}
}
public function submitForm(array &$form, FormStateInterface $form_state){
$mailManager = \Drupal::service('plugin.manager.mail');
$module = 'Registration_form';
$key = 'contact_form'; // Replace with Your key
$to = $form_state->getValue('Email');
$params = array(
'body' => 'test',
'subject' => 'Website Information Request',
);
$langcode = \Drupal::currentUser()->getPreferredLangcode();
$send = true;
$message['subject'] = t('nouveau contact ');
$message['body'][] = t('test');
$result = $mailManager->mail($module, $key, $to, $langcode, $params, NULL, $send);
if ($result['result'] != true) {
$message = t('There was a problem sending your email notification to #email.', array('#email' => $to));
drupal_set_message($message, 'error');
\Drupal::logger('mail-log')->error($message);
return;
}
else{
$message = t('An email notification has been sent to #email ', array('#email' => $to));
drupal_set_message($message);
\Drupal::logger('mail-log')->notice($message);
}
}
So my question is i'm using localhost in xampp and i want to sent a mail after submission of the form, but i'm getting this error
Unable to send email. Contact the site administrator if the problem persists.
There was a problem sending your email notification to ABC#gmail.com
So how I can resolve my problem, i have gone through whole sites but not able to find answer.

The problem may be with the email configuration. See if this article helps you:
