title: How to send email from Contact Form in Drupal 7?
body: <p>Currently, I am developing a website using Drupal 7 in my local computer.
  I have set up Contact Form (Drupal core module) for user to send feedbacks.
  However, I have no idea how to send email from Contact form. I didn't receive any email after I filled in and submitted the contact form. And website displays the status "The message has been sent." But there is no email received.</p>
  
  <p>I know there must be something I need to setup before using Contact Form. Maybe mail server?</p>
  
  <p>I use Drupal 7 with XAMPP.</p>
  
  <p>Is there any step-by-step guideline on sending email? Maybe for both cases</p>
  
  <ol>
  <li>Local machine as web server (for testing on my local computer)</li>
  <li>Real web server (for publishing after everything is done)</li>
  </ol>
  
  <p>I have searched some solutions in some forums but I do not understand.
  I am new to Drupal.
  Thank you so much for your help and guidance.</p>
