Answer 1

I created the Nodemailer transport for mailgun.

Here it how it works.

You install the package with npm install as you would do with any package, then in an empty file:

var nodemailer = require('nodemailer');
var mg = require('nodemailer-mailgun-transport');

// This is your API key that you retrieve from www.mailgun.com/cp (free up to 10K monthly emails)
var auth = {
  auth: {
    api_key: 'key-1234123412341234',
    domain: 'sandbox3249234.mailgun.org'
  }
}

var nodemailerMailgun = nodemailer.createTransport(mg(auth));

nodemailerMailgun.sendMail({
  from: 'myemail@example.com',
  to: 'recipient@domain.com', // An array if you have multiple recipients.
  subject: 'Hey you, awesome!',
  text: 'Mailgun rocks, pow pow!',
}, function (err, info) {
  if (err) {
    console.log('Error: ' + err);
  }
  else {
    console.log('Response: ' + info);
  }
});

Replace your API key with yours and change the details and you're ready to go!

var nodemailer = require('nodemailer');
// send mail with password confirmation
var transporter = nodemailer.createTransport( {
    service:  'Mailgun',
    auth: {
     user: 'postmaster@sandboxXXXXXXXXXXXXXXXX.mailgun.org',
     pass: 'XXXXXXXXXXXXXXXX'   
    }
});
var mailOpts = {
    from: 'office@yourdomain.com',
    to: 'user@gmail.com',
    subject: 'test subject',
    text : 'test message form mailgun',
    html : '<b>test message form mailgun</b>'
};
transporter.sendMail(mailOpts, function (err, response) {
    if (err) {
     //ret.message = "Mail error.";
    } else {
     //ret.message = "Mail send.";
    }
});

It worked me, when I added the domain also to the auth object (not only the api_key). Like this:

var auth = {
  auth: {
    api_key: 'key-12319312391',
    domain: 'sandbox3249234.mailgun.org'
  }
};
