I have set up an email server on my host. It's basically a SMTP server that listens on port 25.
const recvServer = new SMTPServer({
requireTLS: true,
authOptional: true,
logger: true,
onConnect(session, callback) {
return callback();
},
onMailFrom(address, session, callback) {
console.log('from', address, session);
return callback();
},
onData(stream, session, callback) {
console.log('new msg');
let message = '';
stream.on('data', chunk => {
message += chunk;
});
stream.on('end', () => {
callback(null, 'Message queued');
simpleParser(message)
.then(parsed => {
console.log(parsed);
// here I wish to forward the message to outside gmail addresses
})
.catch(err => {
console.log(ee)
});
});
}
});
recvServer.listen(25);
recvServer.on('error', err => {
console.log(err.message);
});
It works fine for receiving emails from outside, like gmail etc.
But I want to be able to send emails outside also, or forward emails that I receive to some gmail addresses.
I know that I can do that using Gmail SMTP servers, but then I need an gmail account and password.
I want to be able to send email with my own server, just like yahoo sends mail to gmail using their own server not gmail accounts :)

- Postfix works fine. If you have your server hosted by a third party, you can usually use their SMTP servers as relay – Moritz Roessler Commented Jun 5, 2019 at 10:41

Reset to default 9 +200You need a MTA (Mail Transfer Agent) in order to send an email.
So the popular options is: Postfix, here a guid how to setup postfix on ubuntu: https://help.ubuntu./munity/Postfix
Or you can spin up a docker container like: https://hub.docker./r/bytemark/smtp/
Then you can use nodemailer to send emails through postfix or docker instance.
And if you want there is a full stack docker image all batteries included: https://github./tomav/docker-mailserver
Technically you can use NodeMailer for sending emails.
"use strict";
const nodemailer = require("nodemailer");
// async..await is not allowed in global scope, must use a wrapper
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: "smtp.ethereal.email",
port: 587,
secure: false, // true for 465, false for other ports
auth: {
user: testAccount.user, // generated ethereal user
pass: testAccount.pass // generated ethereal password
}
});
// send mail with defined transport object
let info = await transporter.sendMail({
from: '"Fred Foo
