我无法使用 Nodemailer 制作邮件系统

Question

我创建这个系统已经几个小时了。我几乎要结束这个项目了，但不知何故，我在填写表格后收不到任何电子邮件。有谁知道这个问题的原因是什么？？首先，我安装了 node.js，然后是 nodemon。我在项目文件夹中有四个主要文件和一个文件夹 - app.js、package-lock.json、contact.handlebars、package.json 和 node_module。

下面的代码是app.js

const express = require("express");
const bodyParser = require("body-parser");
const exphbs = require("express-handlebars");
const path = require("path");
const nodemailer = require("nodemailer");

const app = express();

// view engine setup
app.engine("handlebars", exphbs());
app.set("view engine", "handlebars");

// Static folder
app.use("/public", express.static(path.join(__dirname, "public")));

// Body Parser Middleware
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

app.get("/", (req, res) => {
  res.render("contact", { layout: false });
});

app.post("/send", (req, res) => {
  const output = `
        <p>You have a new contact request</p>
        <h3>Contact Details</h3>
        <ul>
            <li>Name: ${req.body.name}</li>
            <li>Company: ${req.body.company}</li>
            <li>Email: ${req.body.email}</li>
            <li>Phone: ${req.body.phone}</li>
        </ul>
        <h3>Message</h3>
        <p>${req.body.message}</p>
    `;
  async function main() {
    // Generate test SMTP service account from ethereal.email
    // Only needed if you don't have a real mail account for testing
    let testAccount = await nodemailer.createTestAccount();

    // create reusable transporter object using the default SMTP transport
    let transporter = nodemailer.createTransport({
      host: "I PUT 1ST SERVERNAME HERE OF HOSTGATOR",
      port: 587,
      secure: false, // true for 465, false for other ports
      auth: {
        user: "MY 1ST EMAIL ACCOUNT", // generated ethereal user
        pass: "********" // generated ethereal password
      },
      tls: {
        rejectUnauthorized: false
      }
    });

    // send mail with defined transport object
    let info = await transporter.sendMail({
      from: '"Nodemailer Contact" <MY 1ST EMAIL ACCOUNT>', // sender address
      to: "MY SECOND EMAIL ACCOUNT", // list of receivers
      subject: "Node Contact Request", // Subject line
      text: "Hello world?", // plain text body
      html: output // html body
    });

    console.log("Message sent: %s", info.messageId);
    console.log("Preview URL: %s", nodemailer.getTestMessageUrl(info));

    res.render("contact", { layout: false }, { msg: "Email has been sent" });
  }

  main().catch(console.error);
});

app.listen(3000, () => console.log("server started..."));

Ethereal 的测试 SMTP 服务不发送电子邮件。来自他们的网站：

It's a completely free anti-transactional email service where messages never get delivered.

看起来它可以让您查看已发送邮件的预览以检查您的应用程序是否正常工作，但要真正发送电子邮件，您需要设置一个真正的 SMTP 服务器。您可以获得 SMTP 凭据，用于从 SendGrid 和 Mailgun 等不同公司的应用程序发送交易邮件。
