Nodemailer is not working on production with NodeJS and gmail [duplicate]

I try to use nodemailer to implement a contact form using NodeJS but it works only on local it doesn't work on a remote server...
My error message :

[website.fr-11 (out) 2013-11-09T15:40:26] stage: 'auth' }
My controller :
exports.contact = function(req, res){
var name = req.body.name;
var from = req.body.from;
var message = req.body.message;
var to = '*******#gmail.com';
var smtpTransport = nodemailer.createTransport("SMTP",{
service: "Gmail",
auth: {
user: "******#gmail.com",
pass: "*****"
}
});
var mailOptions = {
from: from,
to: to,
subject: name+' | new message !',
text: message
}
smtpTransport.sendMail(mailOptions, function(error, response){
if(error){
console.log(error);
}else{
res.redirect('/');
}
});
}

I solved this by going to the following url (while connected to google with the account I want to send mail from):
https://www.google.com/settings/security/lesssecureapps
There I enabled less secure apps.
Done

See nodemailer's official guide to connecting Gmail:
https://community.nodemailer.com/using-gmail/
-
It works for me after doing this:
Enable less secure apps - https://www.google.com/settings/security/lesssecureapps
Disable Captcha temporarily so you can connect the new device/server - https://accounts.google.com/b/0/displayunlockcaptcha

Easy Solution:
var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');
var transporter = nodemailer.createTransport(smtpTransport({
service: 'gmail',
host: 'smtp.gmail.com',
auth: {
user: 'somerealemail#gmail.com',
pass: 'realpasswordforaboveaccount'
}
}));
var mailOptions = {
from: 'somerealemail#gmail.com',
to: 'friendsgmailacc#gmail.com',
subject: 'Sending Email using Node.js[nodemailer]',
text: 'That was easy!'
};
transporter.sendMail(mailOptions, function(error, info){
if (error) {
console.log(error);
} else {
console.log('Email sent: ' + info.response);
}
});
Step 1:
go here https://myaccount.google.com/lesssecureapps and enable for less secure apps. If this does not work then
Step 2
go here https://accounts.google.com/DisplayUnlockCaptcha and enable/continue and then try.
for me step 1 alone didn't work so i had to go to step 2.
i also tried removing the nodemailer-smtp-transport package and to my surprise it works. but then when i restarted my system it gave me same error, so i had to go and turn on the less secure app (i disabled it after my work).
then for fun i just tried it with off(less secure app) and vola it worked again!

You should use an XOAuth2 token to connect to Gmail. No worries, Nodemailer already knows about that:
var smtpTransport = nodemailer.createTransport('SMTP', {
service: 'Gmail',
auth: {
XOAuth2: {
user: smtpConfig.user,
clientId: smtpConfig.client_id,
clientSecret: smtpConfig.client_secret,
refreshToken: smtpConfig.refresh_token,
accessToken: smtpConfig.access_token,
timeout: smtpConfig.access_timeout - Date.now()
}
}
};
You'll need to go to the Google Cloud Console to register your app. Then you need to retrieve access tokens for the accounts you wish to use. You can use passportjs for that.
Here's how it looks in my code:
var passport = require('passport'),
GoogleStrategy = require('./google_oauth2'),
config = require('../config');
passport.use('google-imap', new GoogleStrategy({
clientID: config('google.api.client_id'),
clientSecret: config('google.api.client_secret')
}, function (accessToken, refreshToken, profile, done) {
console.log(accessToken, refreshToken, profile);
done(null, {
access_token: accessToken,
refresh_token: refreshToken,
profile: profile
});
}));
exports.mount = function (app) {
app.get('/add-imap/:address?', function (req, res, next) {
passport.authorize('google-imap', {
scope: [
'https://mail.google.com/',
'https://www.googleapis.com/auth/userinfo.email'
],
callbackURL: config('web.vhost') + '/add-imap',
accessType: 'offline',
approvalPrompt: 'force',
loginHint: req.params.address
})(req, res, function () {
res.send(req.user);
});
});
};

Worked fine:
1- install nodemailer, package if not installed
(type in cmd) : npm install nodemailer
2- go to https://myaccount.google.com/lesssecureapps and turn on Allow less secure apps.
3- write code:
var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'trueUsername#gmail.com',
pass: 'truePassword'
}
});
const mailOptions = {
from: 'any#any.com', // sender address
to: 'true#true.com', // list of receivers
subject: 'test mail', // Subject line
html: '<h1>this is a test mail.</h1>'// plain text body
};
transporter.sendMail(mailOptions, function (err, info) {
if(err)
console.log(err)
else
console.log(info);
})
4- enjoy!

I had the same problem. Allowing "less secure apps" in my Google security settings made it work!

Non of the above solutions worked for me. I used the code that exists in the documentation of NodeMailer. It looks like this:
let transporter = nodemailer.createTransport({
host: 'smtp.gmail.com',
port: 465,
secure: true,
auth: {
type: 'OAuth2',
user: 'user#example.com',
serviceClient: '113600000000000000000',
privateKey: '-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBg...',
accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x',
expires: 1484314697598
}
});

Same problem happened to me too. I tested my system on localhost then deployed to the server (which is located at different country) then when I try the system on production server I saw this error. I tried these to fix it:
https://www.google.com/settings/security/lesssecureapps Enabled it but it was not my solution
https://g.co/allowaccess I allowed access from outside for a limited time and this solved my problem.

I found the simplest method, described in this article mentioned in Greg T's answer, was to create an App Password which is available after turning on 2FA for the account.
myaccount.google.com > Sign-in & security > Signing in to Google > App Passwords
This gives you an alternative password for the account, then you just configure nodemailer as a normal SMTP service.
var smtpTransport = nodemailer.createTransport({
host: "smtp.gmail.com",
port: 587,
auth: {
user: "username#gmail.com",
pass: "app password"
}
});
While Google recommend Oauth2 as the best option, this method is easy and hasn't been mentioned in this question yet.
Extra tip: I also found you can add your app name to the "from" address and GMail does not replace it with just the account email like it does if you try to use another address. ie.
from: 'My Pro App Name <username#gmail.com>'

It is resolved using nodemailer-smtp-transport module inside createTransport.
var smtpTransport = require('nodemailer-smtp-transport');
var transport = nodemailer.createTransport(smtpTransport({
service: 'gmail',
auth: {
user: '*******#gmail.com',
pass: '*****password'
}
}));

Many answers advice to allow less secure apps which is honestly not a clean solution.
Instead you should generate an app password dedicated to this use:
Log in to your Google account
Go to security
Under Signing in to Google enable 2-Step Verification
Under Signing in to Google click on App passwords.
You'll now generate a new password. Select the app as Mail and the device as Other (Custom name) and name it.
Save the app password
You can now use this app password instead of your log in password.

Try disabling captchas in your gmail account; probably being triggered based on IP address of requestor.
See: How to use GMail as a free SMTP server and overcome captcha

For me is working this way, using port and security (I had issues to send emails from gmail using PHP without security settings)
I hope will help someone.
var sendEmail = function(somedata){
var smtpConfig = {
host: 'smtp.gmail.com',
port: 465,
secure: true, // use SSL,
// you can try with TLS, but port is then 587
auth: {
user: '***#gmail.com', // Your email id
pass: '****' // Your password
}
};
var transporter = nodemailer.createTransport(smtpConfig);
// replace hardcoded options with data passed (somedata)
var mailOptions = {
from: 'xxxx#gmail.com', // sender address
to: 'yyyy#gmail.com', // list of receivers
subject: 'Test email', // Subject line
text: 'this is some text', //, // plaintext body
html: '<b>Hello world ✔</b>' // You can choose to send an HTML body instead
}
transporter.sendMail(mailOptions, function(error, info){
if(error){
return false;
}else{
console.log('Message sent: ' + info.response);
return true;
};
});
}
exports.contact = function(req, res){
// call sendEmail function and do something with it
sendEmail(somedata);
}
all the config are listed here (including examples)

If you use Express, express-mailerwrapsnodemailervery nicely and is very easy to use:
//# config/mailer.js
module.exports = function(app) {
if (!app.mailer) {
var mailer = require('express-mailer');
console.log('[MAIL] Mailer using user ' + app.config.mail.auth.user);
return mailer.extend(app, {
from: app.config.mail.auth.user,
host: 'smtp.gmail.com',
secureConnection: true,
port: 465,
transportMethod: 'SMTP',
auth: {
user: app.config.mail.auth.user,
pass: app.config.mail.auth.pass
}
});
}
};
//# some.js
require('./config/mailer.js)(app);
app.mailer.send("path/to/express/views/some_view", {
to: ctx.email,
subject: ctx.subject,
context: ctx
}, function(err) {
if (err) {
console.error("[MAIL] Email failed", err);
return;
}
console.log("[MAIL] Email sent");
});
//#some_view.ejs
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</html>

For some reason, just allowing less secure app config did not work for me even the captcha thing. I had to do another step which is enabling IMAP config:
From google's help page: https://support.google.com/mail/answer/7126229?p=WebLoginRequired&visit_id=1-636691283281086184-1917832285&rd=3#cantsignin
In the top right, click Settings Settings.
Click Settings.
Click the Forwarding and POP/IMAP tab.
In the "IMAP Access" section, select
Enable IMAP.
Click Save Changes.

all your code is okay only the things left is just go to the link https://myaccount.google.com/security
and keep scroll down and you will found Allow less secure apps: ON and keep ON, you will find no error.

Just add "host" it will work .
host: 'smtp.gmail.com'
Then enable "lesssecureapps" by clicking bellow link
https://myaccount.google.com/lesssecureapps

Google has disabled the Less Secure App Access, Below is New Process to use Gmail in Nodejs
Now you have to enable 2 Step Verification in Google (How to Enable 2 Step Auth)
You need to generate App Specific Password. Goto Google My Account > Security
Click on App Password > Select Other and you will get App Password
You can use normal smtp with email and App password.

exports.mailSend = (res, fileName, object1, object2, to, subject, callback)=> {
var smtpTransport = nodemailer.createTransport('SMTP',{ //smtpTransport
host: 'hostname,
port: 1234,
secureConnection: false,
// tls: {
// ciphers:'SSLv3'
// },
auth: {
user: 'username',
pass: 'password'
}
});
res.render(fileName, {
info1: object1,
info2: object2
}, function (err, HTML) {
smtpTransport.sendMail({
from: "mail#from.com",
to: to,
subject: subject,
html: HTML
}
, function (err, responseStatus) {
if(responseStatus)
console.log("checking dta", responseStatus.message);
callback(err, responseStatus)
});
});
}
You must add secureConnection type in you code.

I was using an old version of nodemailer 0.4.1 and had this issue. I updated to 0.5.15 and everything is working fine now.
Edited package.json to reflect changes then
npm install

Just attend those:
1- Gmail authentication for allow low level emails does not accept before you restart your client browser
2- If you want to send email with nodemailer and you wouldnt like to use xouath2 protocol there you should write as secureconnection:false like below
const routes = require('express').Router();
var nodemailer = require('nodemailer');
var smtpTransport = require('nodemailer-smtp-transport');
routes.get('/test', (req, res) => {
res.status(200).json({ message: 'test!' });
});
routes.post('/Email', (req, res) =>{
var smtpTransport = nodemailer.createTransport({
host: "smtp.gmail.com",
secureConnection: false,
port: 587,
requiresAuth: true,
domains: ["gmail.com", "googlemail.com"],
auth: {
user: "your gmail account",
pass: "your password*"
}
});
var mailOptions = {
from: 'from#gmail.com',
to:'to#gmail.com',
subject: req.body.subject,
//text: req.body.content,
html: '<p>'+req.body.content+' </p>'
};
smtpTransport.sendMail(mailOptions, (error, info) => {
if (error) {
return console.log('Error while sending mail: ' + error);
} else {
console.log('Message sent: %s', info.messageId);
}
smtpTransport.close();
});
})
module.exports = routes;

first install nodemailer
npm install nodemailer --save
import in to js file
const nodemailer = require("nodemailer");
const smtpTransport = nodemailer.createTransport({
service: "Gmail",
auth: {
user: "example#gmail.com",
pass: "password"
},
tls: {
rejectUnauthorized: false
}
});
const mailOptions = {
from: "example#gmail.com",
to: sending#gmail.com,
subject: "Welcome to ",
text: 'hai send from me'.
};
smtpTransport.sendMail(mailOptions, function (error, response) {
if (error) {
console.log(error);
}
else {
console.log("mail sent");
}
});
working in my application

You may need to "Allow Less Secure Apps" in your Gmail account (it's all the way at the bottom). You also may need to "Allow access to your Google account".
You also may need to "Allow access to your Google account".

This is my Nodemailer configuration which worked after some research.
Step 1: Enable lesssecureapp
https://www.google.com/settings/security/lesssecureapps
Step 2: The Nodemailer configuration for Gmail
Setting up the transporter : A transporter is going to be an object that can send mail. It is the transport configuration object, connection URL, or a transport
plugin instance
let transporter = nodemailer.createTransport({
service: 'gmail', // the service used
auth: {
user: process.env.EMAIL_FROM, // authentication details of sender, here the details are coming from .env file
pass: process.env.EMAIL_FROM_PASSWORD,
},
});
Writing the message
const message = {
from: 'myemail#gmail.com', // sender email address
to: "receiver#example.com, receiver2#gmail.com", // reciever email address
subject: `The subject goes here`,
html: `The body of the email goes here in HTML`,
attachments: [
{
filename: `${name}.pdf`,
path: path.join(__dirname, `../../src/assets/books/${name}.pdf`),
contentType: 'application/pdf',
},
],
Sending the mail
transporter.sendMail(message, function (err, info) {
if (err) { // if error
console.log(err);
} else {
console.log(info); // if success
}
});

I also had issues with nodemailer email sending when running on Vercel lambda in production.
What fixed it in my case was to await for sendMail Promise to resolve.
I also added nodemailer-smtp-transport like suggested in this thread but I don't think it made a difference.
Here is my whole function:
const nodemailer = require('nodemailer');
const smtpTransport = require('nodemailer-smtp-transport');
const transporter = nodemailer.createTransport(smtpTransport({
service: 'gmail',
auth: {
user: '***#gmail.com',
pass: process.env.SMTP_PASSWORD,
},
}));
async function contact(req: any, res: any) {
try {
const response = await transporter.sendMail({
from: '"*** <***gmail.com>', // sender address
to: "***#gmail.com", // list of receivers
subject: `***`, // Subject line
html: `${req.body.message}<br/><br/>${req.body.firstname} ${req.body.lastname} - <b>${req.body.email}</b>`, // html body
});
} catch (error: any) {
console.log(error);
return res.status(error.statusCode || 500).json({ error: error.message });
}
return res.status(200).json({ error: "" });
}
export default contact;

As pointed out by Yaach, as of May 30th, 2022, Google no longer supports Less Secure Apps, and instead switched over to their own Gmail API.

Here is the sample code for Gmail SMTP with nodemailer.
"use strict";
const nodemailer = require("nodemailer");
async function main() {
let transporter = nodemailer.createTransport({
host: "smtp.gmail.com",
transportMethod: "SMTP",
secureConnection: true,
port: 465,
secure: true, // upgrade later with STARTTLS
auth: {
user: "yourEmail#gmail.com",
pass: "Your App Specific password",
},
});
let info = await transporter.sendMail(
{
from: "yourEmail#gmail.com",
to: "to#gmail.com",
subject: "Testing Message Message",
text: "I hope this message gets delivered!",
html: "<b>Hello world?</b>", // html body
},
(err, info) => {
if (err) {
console.log(err);
} else {
console.log(info.envelope);
console.log(info.messageId);
}
}
);
}
main();

Less secure option is not supported anymore by gmail.
For sending email from third party, gmail is also not allowing with its user password.
You should now use App Password to resolve this issue.
Hope this link will help to set your app password.
https://support.google.com/mail/answer/185833?hl=en

There is another option to use SendGrid for email delivery with no failure. A lot of the time, Nodemailer gives failure for mail which could happen frequently.
Nodemailer can be found in the link.

TypeError - invalid login

I wrote some code to implement nodemailer in my nodejs application to send mails.
i wrote this code:
var express = require("express");
var router = express.Router();
var nodemailer = require("nodemailer");
/* GET contact page. */
router.get("/", function (req, res, next) {
res.render("contact", { title: "Contact" });
});
router.post("/send", function (req, res, next) {
var transporter = nodemailer.createTransport({
service: "Gmail",
auth: {
user: "MyEmailHere",
pass: "password",
},
tls: {
rejectUnauthorized: false
}
});
var mailOptions = {
from: "MyEmailHere",
to: "myOtherEmailId",
subject: "Website Submission",
text:
"You have a new submission with the following details...Name: " +
req.body.name +
" Email: " +
req.body.email +
" Message: " +
req.body.message,
html:
"<p> You got a new submission with the following details...</p><ul></ul><li>Name: " +
req.body.name +
"</li><li>Email: " +
req.body.email +
"</li><li>Message: " +

};
transporter.sendMail(mailOptions, function (error, info) {
if (error) {
console.log(error);
res.redirect("/");
} else {
console.log("Message Sent: " + info.response);
}
});
});
module.exports = router;
But I get an error saying: "Username and password not accepted." Am i supposed to use my real password? Does nodemailer also support Yahoomail besides Gmail? I am still learning and in dev mode by the way. A little help?

It worked flawlessly when I entered my own information correctly and turned on 'less secure apps', please try it this way
NOTE (critical): make sure the 'less secure apps' option is turned on

Yes, you need to enter your real information and I recommend you to read this text.
Even though Gmail is the fastest way to get started with sending
emails, it is by no means a preferable solution unless you are using
OAuth2 authentication. Gmail expects the user to be an actual user not
a robot so it runs a lot of heuristics for every login attempt and
blocks anything that looks suspicious to defend the user from account
hijacking attempts. For example you might run into trouble if your
server is in another geographical location – everything works in your
dev machine but messages are blocked in production.
Additionally Gmail has came up with the concept of “Less Secure” apps which is
basically
anyone who uses plain password to login to Gmail, so you might end up
in a situation where one username can send mail (support for “less
secure” apps is enabled) but other is blocked (support for “less
secure” apps is disabled). You can configure your Gmail account to
allow less secure apps here. When using this method make sure to also
enable the required functionality by completing the “Captcha Enable”
challenge. Without this, less secure connections probably would not
work.
And make sure the 'less secure apps' option is turned on

req.body.name is not defined - Nodemailer ejs

I saw some problems which are close to mine but not exactly the same so my issue is I got a ejs template with a Form attribut and I want to send the input to a mail so I declare all input with name="xyz" and inside the routes.get: req.body.conSurname, conName: req.body.conName,. So my post route looks like this.
router.post('/contact/send', (req, res) => {
// Nodemailer
let transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: 'abc#gmail.com',
pass: '******'
}
});
const mailOptions = {
from: 'abc#gmail.com',
to: 'def#gmx.de',
subject: 'New Mail',
html: '<h2>Mail from: '+ req.body.conSurname + ' ' + conName + '</h2>'
};
transporter.sendMail(mailOptions, function (err, info) {
if (err)
console.log(err)
else
console.log(info);
});
res.redirect('/contact');
})
If I send the formular it throws ReferenceError: conSurname is not defined but if I log one attrubut it shows me the correct value from the input.
Where is the error?

That's because you have to import the json middleware like this:
var express = require('express');
var app = express();
app.use(express.json());
Then your express server will deserialize JSON bodies when receiving requests with the Content-Type: application/json header, and your code will work correctly.

How to store email in variables and send it with node.js

const functions = require('firebase-functions');
var nodemailer = require('nodemailer');
var transporter=nodemailer.createTransport('smtps://username#gmail.com:password#smtp.gmail.com');
exports.sendMail=functions.https.onRequest((req,res)=>{
var mailOptions={
to: 'sender#gmail.com',
subject: 'Test Mail',
html: 'Testing with Node.js'
}
transporter.sendMail(mailOptions,function(err,response){
if(err)
{
res.send('Mail not sent');
console.log(err);
}
else{
res.send('Mail sent');
}
});
});
I want to send email to various persons over time. I want to change the to: address in this code dynamically. So how to get a particular(sendermailid) variable from another javascript file and send to that person. My folders are located as below the picture.
How to get the variable from assmt.js to index.js(cloud function js).

You need to set up an express server who is listening our other JS aplication like this :
var express = require('express');
var app = express();
Now you can listen from another app on specified port :
var port = process.env.PORT || 8080;
app.listen(port);
console.log("App listening on port " + port);
Finally you have to intercept http post request to send your mail and get user info from the request :
app.post('/api/sendmail', function(req, res) {
var mail = {
from: req.body.user.emailFrom,
to: req.body.user.emailTo,
subject: "your subject",
html: "<p>email body</p>"
}
transporter.sendMail(mail, function(error, response){
if(error){
console.log("Error!");
console.log(error);
res.send(JSON.stringify(error));
}else{
res.send(JSON.stringify(response));
console.log("Success!")
transporter.close();
}
}
Your server is now ready you can start it with :
node serverName.js
And in your other js file ( assmt.js ) you send the http request with parameter :
send(user : User) {
let body = {user};
this.httpClient.post('http://localhost:8080/api/sendconge', body)
.subscribe(function(data) {
console.log(data);
});
}

Nodemailer with Express App won't send email on Button click

Using the default set up from the Nodemailer, the email will send with our internal mail server just fine when the app starts up with all code included on the app.js page.
//app.js
var nodemailer = require('nodemailer');
var transporter = nodemailer.createTransport({
host: 'mail.oursite.com',
});
var mailOptions = {
from: 'couponrequest#company.com', // sender address
to: 'myaddy#company.com', // list of receivers
subject: 'Hello ✔', // Subject line
text: 'Hello world ✔', // plaintext body
html: '<b>Hello world ✔</b>' // html 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);
});
Then when switching things around it breaks and nothing happens when trying to make it happen from a button click.
App.js:
var nodemailer = require('nodemailer');
app.get('/users', routes.users);
Users.js
var express = require('express');
var router = express.Router();
var nodemailer = require('nodemailer');
/*
* POST to addcoupon Request.
*/
router.post('/addcoupon', function(req, res) {
// create reusable transporter object using SMTP transport
var transporter = nodemailer.createTransport({
host: 'mail.primeshine.com',
});
});
module.exports = router;
Index.js
var express = require('express');
var router = express.Router();
var nodemailer = require('nodemailer');
/*
* POST to addcoupon Request.
*/
router.post('/addcoupon', function(req, res) {
// create reusable transporter object using SMTP transport
var transporter = nodemailer.createTransport({
host: 'mail.primeshine.com',
});
});
module.exports = router;
Global.js
// Add Coupon Request
function addCoupon(event) {
event.preventDefault();
var mailOptions = {
from: 'couponrequest#company.com', // sender address
to: 'myaddy#company.com', // list of receivers
subject: 'Hello ✔', // Subject line
text: 'Hello world ✔', // plaintext body
html: '<b>Hello world ✔</b>' // html 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);
});
};
I tried to use only the relevant code to send it. It works fine sending info to MongoDB for the button when it is adding user info but it doesn't submit anything when I try to have it send an email. Not sure if I have something in the wrong place or if something else is wrong... Thanks in advance for any help!

When I used nodemailer to send emails from my email account I had to create the transport with authentication:
/* define transportation */
var transport = nodemailer.createTransport(smtpTransport({
host: 'posteo.de',
port: 465,
secure: true,
auth: {
user: 'username',
pass: 'password'
},
maxConnections: 5,
maxMessages: 10
}));
Not sure if this if this is necessary for in your case but maybe it helps.
