title: Send mail with nodejs
body: <p>For a school project I have to build a website and all the stuff...
  I want to send an email when a certain button is pressed. For now  I used an gmail address for the server BUT it needs authentification and all. How can I bypass the authentification ? Are there some other STMP servers that do not require authentification so I send an email easily ?</p>
  
  <p>Thanks guys !</p>
