使用nodemailer发送电子邮件

我正在尝试使用nodemailer从我的应用程序发送电子邮件。

我的设置如下所示：

var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');
var transporter = nodemailer.createTransport(smtpTransport ({
  host: 'smtp.companyname.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);
    }
});

运行此命令后，它给了我以下错误：

我已经被这个问题困扰了好几天了，到处都是，所以我希望有人可以帮助我（或者至少指向正确的方向）。
