sending mail with nodemailer - node.js

Question

whenever i run the code I'm getting the error " Error: Greeting never received at SMTPConnection._formatError...."
function automatedMailSender(req,res){
var mailOptions = {
from: "abc <abc#test.com>", // sender address
to: 'nit#test.com', // list of receivers
subject: 'Hello ', // Subject line
text: 'Hello world ?', // plain text body
html: '<b>Hello world ?</b>' // html body
};
var mailer=nodemailer.createTransport({
host: 'mail.test.com',
port: 465,
secure: false, // secure:true for port 465, secure:false for port 587
auth: {
user: 'mymail#test.com',
pass: '1234'
}
});
mailer.sendMail(mailOptions, (error, response)=>{
if(error){
console.log('mail not sent \n',error);
}
else{
console.log("Message sent: " ,response.message);
}
});
}
I'm I doing something wrong in the code.

Answer 1

The answer in right in your code
port: 465,
secure: false, // secure:true for port 465, secure:false for port 587
The value for "secure" should be true for port 465

Answer 2

If you are using Gmail to send mails then try this.
Allow less secure apps to connect to Gmail.

Answer 3

Try something like that, it work perfectly for me:
//Create reusable transporter object using the default SMTP transport
var transporter = nodemailer.createTransport(
'smtps://USERNAME%40gmail.com:PASSWORD#smtp.gmail.com');
// setup e-mail data
var mailOptions = {
from: '"Michel 👥" <recipe#example.com>', // sender address
to: 'bernard#example.com', // list of receivers
subject: 'Hello', // Subject line
text: 'Bonjour!' // plaintext body
};
// send mail with defined transport object
transporter.sendMail(mailOptions, function(error, info){
if(error){
return console.log(error);
}
console.log('Message sent: ' + info.response);
});
If is still doesn't work you have a little tuto here

Answer 4

var mailer=nodemailer.createTransport({
host: 'mail.test.com',
port: 465,
secure: true, // secure:true for port 465, secure:false for port 587
transportMethod: 'SMTP',
auth: {
user: 'mymail#test.com',
pass: '1234'
}
});
The value for secure should be true for port 465 and use transportMethod: 'SMTP'

const express = require('express');
const router = express.Router();
const { Email } = require('../models/email.model');
const { User } = require('../models/user.model');
const nodemailer = require('nodemailer');
//post email
router.post('/send', async (req, res) => {
if (req.query) {
var query = {}
if (req.query.lastname) { query.lastname = req.query.lastname }
if (req.query.firstname) { query.firstname = req.query.firstname }
if (req.query.email) { query.email = req.query.email }
if (req.query.isactive) { query.isActive = req.query.isactive }
if (req.query.isgain) { query.isGain = req.query.isgain }
}
const email = new Email({
title: req.body.title,
subject: req.body.subject,
text: req.body.context,
description: req.body.description
});
if (req.body.title && req.body.subject && req.body.context) {
const user_db = await User.find(query)
const user_db_email = user_db.map(x => x.email)
var smtpTransport = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: { user: 'ghiles#gmail.com', pass: 'g' },
tls: { rejectUnauthorized: false }, // do not fail on invalid certs
});
var mailOptions = {
to: user_db_email,
from: 'fatb#gmail.com',
subject: req.body.subject,
text: req.body.context
};
email.save().then(() => {
smtpTransport.sendMail(mailOptions)
.then(() => res.status(200).json(email))
.catch(() => res.status(500).json({ success: false, message: `erreur dans l'envoi de mail` }))
}).catch(() => res.status(200).json({ success: false, message: `erreur dans le serveur` }))
} else {
res.status(400).json({ success: false, message: `Veuillez renseigner le titre et l'objet et le contexte du mail` })
}
module.exports = router;

Answer 6

tls:{
rejectUnauthorized:false
}
fixed it by using the above code in mailer variable.
Thanks guys

Answer 7

host: 'smtp.host.com',
port: 587, // 587 or 25 or 2525
secure: false, // secure:true for port 465, secure:false for port 587
auth: {
user: 'mymail#test.com',
pass: '1234'
}
Try this. prefixing smtp and changing the port.
