Nodemailer：ECONNREFUSED

Question

我不知道自己缺少什么，我使用Nodemailer示例：

var nodemailer = require("nodemailer");

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

// setup e-mail data with unicode symbols
var mailOptions = {
    from: "Fred Foo ✔ <[e-mail]>", // sender address
    to: "[e-mail], [e-mail]", // 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
});

我只是更改了用户并将auth传递给我的gmail帐户信息（也尝试了其值），然后将“至”电子邮件地址更改为我的电子邮件地址。我得到：

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

我想念什么？我在文档中看不到任何说明我需要做的事情，为什么它不起作用？先感谢您。

这是一个防火墙问题。原来代码没有错，我只是不明白错误消息的含义。
