Unable to Send Mail through node-mailer

Question

So I was recently working on an app(in java-script) where I was building the forgot-password and reset-password Module.

What I was trying to do was to send an JWT the mail specified using the Mail-trap service.

Down below are the codes where that I have written to pass...

Forgot Password

    exports.forgotPassword = catchAsync(async (req, res, next) => {
  // 1) Get User based on posted email
  const user = await User.findOne({ email: req.body.email });
  if (!user) {
    return next(new AppError('There is no user with the email address', 404));
  }

  // 2) Get Reset Token
  const resetToken = user.createPasswordResetToken();
  await user.save({ validateBeforeSave: false });

  //3 Send Mail to user
  const resetURL = `${req.protocol}://${req.get(
    'host'
  )}/api/v1/users/resetPassword/${resetToken}`;

  const message = `Forgot your password? Submit a PATCH Request to passwordConfirm to : ${resetURL}. \n If you did not send this request please ignore the email`;

  await sendEmail({
    email: user.email,
    subject: 'Your Password Reset Token Valid For 10 Minutes.',
    message
  });

  res.status(200).json({
    status: 'success',
    message: 'Token sent to email'
  });
});

The email.js file

const nodemailer = require('nodemailer');

const sendEmail = async options => {
  // 1) Create Transporter
  const transporter = nodemailer.createTransport({
    host: process.env.EMAIL_HOST,
    port: process.env.EMAIL_PORT,
    auth: {
      user: process.env.EMAIL_USERNAME,
      pass: process.env.EMAIL_PASSWORD
    }
  });

  //2 Define Mail Options
  const mailOptions = {
    from: 'Admin <[email protected]>',
    to: options.email,
    subject: options.subject,
    text: options.message
  };

  await transporter.sendMail(mailOptions);
};

module.exports = sendEmail;

I have no code errors from the visual studio code, have double checked spellings while I was debugging the code, though there was one error that I found while trying to install nodemailer...

error code NodeMaile: -

Thank you for using Nodemailer for your email sending needs! While Nodemailer
itself is mostly meant to be a SMTP client there are other related projects in
the Nodemailer project as well.

For example:
> IMAP API (  https://imapapi.com  ) is a server application to easily access
IMAP accounts via REST API
> NodemailerApp (  https://nodemailer.com/app/  ) is a cross platform GUI app to
debug emails

}

Someone please help me with this. This happens to be an very important functionality in the app due to which another module is suffering.

Answer 1

I was trying this with mailtrap.io and after spending much time the problem was that the "auth" was not reading the "process.env.EMAIL_PASSWORD" from the config.env file.

const transporter = nodemailer.createTransport({
    host: process.env.EMAIL_HOST,
    port: process.env.EMAIL_PORT,
    auth: {
        user: process.env.EMAIL_USERNAME,
        pass: "process.env.EMAIL_PASSWORD"
    }
});

So I had to write it manually in the auth like this and also changed port to 578

const transporter = nodemailer.createTransport({
    host: process.env.EMAIL_HOST,
    port: process.env.EMAIL_PORT,
    auth: {
        user: process.env.EMAIL_USERNAME,
        pass: "8d984726187121"
    }
});

Answer 2

I was getting the same error

Error: connect ETIMEDOUT 3.209.246.195:587
at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16) 

{  
errno: -4039,  
code: 'ESOCKET',  
syscall: 'connect',  
address: '3.209.246.195',  
port: 587,
command: 'CONN'
}

I tried to debug it for an hour. Then I changed my internet and it fixed the issue. Slow internet was the problem in my case. But the error was the same. timeout.

Answer 3

in your

const transporter = nodemailer.createTransport({
    host: process.env.EMAIL_HOST,
    port: process.env.EMAIL_PORT,
    auth: {
      user: process.env.EMAIL_USERNAME,
      pass: process.env.EMAIL_PASSWORD
    }
  });

could you add

   tls:{
    rejectUnauthorized: false
}

to make it

const transporter = nodemailer.createTransport({
    host: process.env.EMAIL_HOST,
    port: process.env.EMAIL_PORT,
    auth: {
      user: process.env.EMAIL_USERNAME,
      pass: process.env.EMAIL_PASSWORD
    },
    tls:{
    rejectUnauthorized: false
    }
  });

this should fix your problem as you can now self authenticate yourself

Hopefully, this fixed your problem. If you are still having problems give this a read: https://github.com/MarkCavalli/rageserver/issues/51
