Nodemailer: ECONNREFUSED

I don't know what I'm missing, I use the Nodemailer example:

var nodemailer = require("nodemailer");

// create reusable transport method (opens pool of SMTP connections)
var smtpTransport = nodemailer.createTransport("SMTP",{
    service: "Gmail",
    auth: {
        user: "[email protected]",
        pass: "userpass"
    }
});

// setup e-mail data with unicode symbols
var mailOptions = {
    from: "Fred Foo ✔ <[email protected]>", // sender address
    to: "[email protected], [email protected]", // 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
smtpTransport.sendMail(mailOptions, function(error, response){
    if(error){
        console.log(error);
    }else{
        console.log("Message sent: " + response.message);
    }

    // if you don't want to use this transport object anymore, uncomment following line
    //smtpTransport.close(); // shut down the connection pool, no more messages
});

I just changed the user and pass in auth to my gmail account info (also tried with their values), and I changed the "to" email address to my email address. I get:

{ [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect' }

What am I missing? I don't see anything in the documentation that says I need to do anything more than this, so why won't it work? Thank you in advance.

It was a firewall issue. Turns out there was nothing wrong with the code, I just didn't understand what the error message implied.

Following step:

1. Login gmail account.

2. Enable pop3 in settings tabs

3. Enable less secure apps at: Enable less secure apps for gmail account

4. Display Unlock Captcha at: Display unlock Captcha

5. Defined email option and sending

   var mailOptions = {
       host: 'smtp.gmail.com',
       port: 465,
       secure: true, // use SSL
       auth: {
           user: '[email protected]',
           pass: 'password'
       }
   }    
   
   mailer = nodemailer.createTransport(mailOptions);
   
   mailer.sendMail({
   ....
   }, function(err, response) {
           if (err) {
                console.log(err);
           }
           console.log(response);
   });
   

Hope this block code help you.

I was also using a gmail account to send the email, you might need an Application-specific password from google to allow nodemailer to work properly.

ECONNREFUSED inidcates that this is some kind of connection or firewall issue.

Can you connect to smtp.gmail.com port 465 with any other application from the same machine, for example with openssl?

openssl s_client -connect smtp.gmail.com:465
