Send email with nodemailer, centOS

Hello everyone,

I have a express.js app installed in a centOS server. I have a code that in my local environment works fine, but in the centOS doesn’t work.

Here is the code:

const nodemailer = require('nodemailer');
const transporter = nodemailer.createTransport({
  service: 'gmail',
  options: {
    debug: true
  },
  auth: {
    user: "user@gmail.com",
    pass: " ********* "
  }
});

…

transporter.sendMail(mailOptions, (err, info) => {
      if(err){
        console.log(err);
        return res.render('index.html', {HOME: req.home, mensagem: 'Erro no envio de mensagem', erro: 1});
      }
      return res.render('index.html', {HOME: req.home, mensagem: 'Email enviado com sucesso', erro: 0});
  })

It’s a nodemailer module from npm. I tried to check with there is any mistake on my SMTP port, but i didn’t find anything.

Thanks!
