Can't send mail with Cloud Functions for Firebase

问题

I'm trying to send an email from a Cloud Function using the sendmail package. It works when I host my "send function" locally. And I can deploy the function without problems to my Firebase project.

In the log at Firebase I can see this message:

Error: queryMx ESERVFAIL hotmail.com
at errnoException (dns.js:28:10)
at QueryReqWrap.onresolve [as oncomplete] (dns.js:219:19)

I'm neither familiar with sending emails from servers or Cloud Functions for Firebase. My question is why I got this error and how I can make it work?

Here is an excerpt from my function:

sendmail({
        from: body.name + ' ' + '<' + body.email + '>',
        to: 'soerensmed@hotmail.com',
        subject: 'Henvendelse via kontaktformular',
        html: html,
    }, function (err, reply) {
        if (err) {
            console.log(err && err.stack);
            response.status(500).end()
        }
        else {
            console.log(reply)
            response.status(200).end()
        }
    });

I'm developing a website where people can contact me through a contact form. The goal is to receive an email with the message... If this approach isn't possible I'm open for suggestions on how I can set this contact-email-thing up using Angular and Firebase.

It will not work with cloud function with free spark account. You should upgrade as it is clearly defined in pricing section in network box. https://firebase.google.com/pricing/
