HI everyone!
I have built a WebRTC app for video, audio and file transfer. But the last requirement is that users invite their friends on to the platform to chat with them. So my question is how do I achieve that with nodemailer without using my email as the sender but rather the users' email.
Hi everyone, I'm trying to attach files to my emails being sent with Nodemailer. Emails are going through, but the issue is that I don't receive the attachments, I need to attach a jpg image, tried with that and text too but no success. I'm using Gmail for both sender and receiver. Anyone any clue? It would be much appreciated.

Hi Guys,
i want to use nodemailer with sendmail but got:

{ Error: connect ECONNREFUSED
at Object.exports._errnoException (util.js:1018:11)
at exports._exceptionWithHostPort (util.js:1041:20)
at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1090:14)
syscall: 'connect',
address: '',
port: 25,
command: 'CONN' }

telnet works

$ telnet 25
Connected to
Escape character is '^]'.
220 bla@blub.tld ESMTP Postfix (Ubuntu)

iptables is configured to accept allr outgoing

Do you have any advice why i got this connection refused?
Ah okay i think i found my error. It was caused by configuration problems because i used nodemailer inside a docker container.
but thanks anyway

Okay my error still exists but i am able to send a mail from the guest os (docker container) through the host os postfix (MTA).
It seem to my that nodemailer tries to open a connection to the MTA of the guest os (docker container) which has no MTA installed.
My first assumption was that the nodemailer-sendmail-transport is not spawning the proper command and put a log out before to inspect the spawned command and args but this section is never reached.

So, is nodemailer open a connection to during transport creation?
Can i configure this behavior?
Because i only need to spawn the sendmail command to get my sending a email issue working ... ?

Ah i forgot I am using the nodemailer version 2.7.0 and sendmail-transport 1.0.2

Can you guys please help me and provide an advice how to solve the last remaining config issue for my problem?


Okay now i upgraded to version 4.0.1 and use the internal sendmail feature.
This gives me the success callback but the mail is not send.

sendmail command spawned: /usr/sbin/sendmail [ '-i', '-f', 'blah@blub.de', 'test@gmail.com' ]

Result is:
Mail send { envelope:
{ from: 'blah@blub.de',
to: [ 'test@gmail.com' ] },
messageId: '18db223c-6e90-a629-4c2e-e6647a939bc6@blub.de',
response: 'Messages queued for delivery' }

i logged the spawned command then and use it manualy in the terminal and my mail was send.
This is a curious behaviour. (@.@)

Anyone have an idea about this?

I am developing a pure node App (without express or any other framework)
I stored some values in the req (request) object like this

req.token = uuid();

in another route, when I did this


I get undefined. Please is there a sure way of saving value into the http request object for later use?

Hi guys, have you guys is the templateSender function for built in templating gone in nodemailer 4.1.0? Looking in tutorials this was the function needed to do builtin templating
I've set X-Mailer header but it always return "X-Mailer: nodemailer (2.7.2; +https://nodemailer.com/; SMTP/2.7.4[client:2.12.0])"
Can I override X-Mailer header? thanks

Hi all, I am wondering why the following:

from: req.params.name + ' <' + req.params.email + '>',

keeps returning the error: Domain of sender address XXXXXX@gmail.com&#62 does not exist

It does not seem to like the "right-tag" on at the end.
Joe Early
from: req.params.name + ' ' + req.params.email,
This worked fine :shipit:

HI all, quick question if someone can answer. I am trying to send in a contact form, and when its "message" is larger than 260 char, it fails to complete the request.
Running expressjs and I think its an issue there but am asking in here just in case
while sending email How to cache the template file so that it will not compile for each request?

Hello, it is possible to send mail to multi users(example to:'o@gmail.com, s@gmail.com...'). But when they receive mail in field receive user seen just his email(not list of all receivers)?

@UaSensei do you mean cc and bcc? if it is then nodemailer does support it.

Is there any example to show how to use nodemailer-build-attachment with nodemailer.
Alexander Escamilla
Please mention me. Apple mail Mac/iphone does not show my pdf attachment. I am using nodemailer and AWS to send out emails. It works well on Chrome though. Here is my attachment config.
            path: path + pdfFileName,
            filename: pdfFileName,
            contentType: 'application/pdf'

Good day everyone, I have an interesting problem i was hoping you could help me with. I just deployed my nodejs/express site live out into the wild onto a digital ocean droplet with a domain name pointing to it and everything! 🤘 Everything was going great until i noticed spam bots submitting bogus data to my contact form which i'm using nodemailer to send. I set up a hidden honeypot field that cancels form submission if not empty, i thought that would do it, but no luck. I searched the internet, npm for packages and stackoverflow high and low for a solution and came up with nothing. If anyone has any suggestions, i would be all ears! Thank you in advance for your help 😊

Just in case anyone was curious. I was able to get it done with the NPM package email-existence. Thanks all for the help.
Existence is determined by telnetting to the MX server of the email domain and attempting to send an email to the supplied address. MX servers return 250 if the email address exists and 550 if it does not.
app.post("/products/contactCorporate", function (req, res) {
  let { name, email, message, businessAddress } = req.body;

  emailExistence.check(email, function (error, response) {
    if (response === false) {
      req.flash('success', 'Sorry, the email seems to be spam!');
    } else {
Is @types/nodemailer up to date?

Hello, I'd like to run a smtp server in my tests to catch outgoing emails. I'm testing smtp-server + nodemailer.
const { SMTPServer } = require('smtp-server');
const nodemailer = require('nodemailer');

const SMTPServerInstance = new SMTPServer({
  logger: true,
  debug: true,
  authOptional: true

SMTPServerInstance.listen(() => {
  console.log('SMTP server is listening!\n');

  const transporter = nodemailer.createTransport({
    logger: true,
    debug: true,
    host: SMTPServerInstance.server.address().address,
    port: SMTPServerInstance.server.address().port,
    ignoreTLS: true

  console.log('Sending email...');
      from: 'sender@example.com',
      to: 'receiver@example.com',
      subject: 'Subject',
      text: 'Text',
      html: 'HTML'
    .then((info) => {
      console.log('Email successfully sent!', info);
    .catch((err) => {
      console.log('Error when sending an email:', err);
    .finally(() => {
I'm not sure why I set ignoreTLS: true on the client. I'd like to disable any auth/encryption on the server, the client should adapt by itself.
