Solution

Using nodemailer to send an email with outMail.

The below example demonstrates how to send an email with plain text and HTML body

"use strict";
const nodemailer = require("nodemailer");

async function main() {
  // create transporter object using the default SMTP transport
  let transporter = nodemailer.createTransport({
    host: "mxXXXXX.smtp-engine.com",
    port: 587,
    secure: false, // This example has TLS off
    auth: {
      user: "outMail-username",
      pass: "outMail-password",
    },
  });

  // send mail with defined transport object
  let info = await transporter.sendMail({
    from: '"My Name" <me@example.com>', 
    to: "toAddress@example.com", 
    subject: "Subject goes here...",
    text: "Hello world",
    html: "Hello world",
  });

  console.log("Message sent: %s", info.messageId);
}

main().catch(console.error);
