I'm trying to send emails from my application using nodemailer.

My setup look like this:

var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');
var transporter = nodemailer.createTransport(smtpTransport ({
  host: 'smtppanyname.dk',
  secureConnection: true,
  port: 587,
  auth: {
        user: '[email protected]',
        pass: '****'
  }
}));

var mailOptions = {
    from: 'Olaf <[email protected]>',
    to: '[email protected]',
    subject: 'This is a test ',
        text: 'Hello world ',
        html: '<b>Hello world </b>'
    };

transporter.sendMail(mailOptions, function(error, info){
    if(error){
       console.log(error);
    }else{
    console.log('Message sent: ' + info.response);
    }
});

After running this, it gives me the following error:

I've been stuck with this for days now and looked everywhere, so I hope somebody can help me with this (or at least point at the right direction).

Try adding:

    tls: {
        rejectUnauthorized: false
    },

To your nodemailer options object.

After adding what @Richard Macarthy suggested, and looking up the new error I got back, I figured out that the from email in my mailOptions has to be the same as the email I'm using to send the emails from - which actually makes perfectly sense now.

In this case:

var mailOptions = {
    from: 'Olaf <[email protected]>',
    to: '[email protected]',
    ...

var transporter = nodemailer.createTransport({<br>
host: 'hostSTMP',
secure: false, //disable SSL    
requireTLS: true, //Force TLS
    tls: {
        rejectUnauthorized: false
    },
    port: port, //Port of STMP service
    auth: {
      user: '[email protected]',
      pass: 'password'
   }
});

rejectUnauthorized: If true, the server certificate is verified against the list of supplied CAs. An error event is emitted if verification fails; Default: true.

rejectUnauthorized: If false, you're saying "I don't care if I can't verify the server's identity."
