title: Why does SMTP via gmail work locally but not on my production server?
body: <p>I'm running a nodejs server hosted on AWS (Ireland) and using emailjs to send emails. The email account I'm using is a gmail account and I can send emails from my local machine without any issues, but the emails fail to send from the production server.</p>
  
  <p>Outbound firewall is set to allow all traffic on all ports.</p>
  
  <p>The error message I get is "authorization.failed".</p>
