title: Nodemailer + Open relay server
body: <p>Is there any documentation on : "How to send an email via open relay SMTP server" (i.e without passing any authentication data) while sending emails.</p>
  
  <p>I tried "SMTP" option with passing just hostname and port# and removing "auth" data and did not work. I am wondering if any of you had similar requirement through node js. And possible ways leading to resolution ?</p>
