MAIL_URL does not work on * as described in the documentation #1649

The documentation here states that the default Mailgun MAIL_URL may be overridden by setting process.env.MAIL_URL, however this does not appear to be the case. The documentation states:

For apps deployed with meteor deploy, MAIL_URL defaults to an account (provided by Mailgun) which allows apps to send up to 200 emails per day; you may override this default by assigning to process.env.MAIL_URL before your first call to Email.send.

However, Mailgun is always used despite the process.env.MAIL_URL setting. To reproduce:

  1. create new meteor app

  2. add below js code

  3. modify code to specific smtp provider (such as from Mandrill) and appropriate from and to email addresses

  4. deploy to a * domain using meteor deploy

  5. visit the domain and click the button

  6. verify that email is from Mailgun and not the smtp provider specified in process.env.MAIL_URL

    if (Meteor.isClient) {
      Template.hello.greeting = function () {
        return "Welcome to testmail.";
        'click input' : function () {    
                'Hello from Meteor!',
                'This is a test of Email.send.');           
    if (Meteor.isServer) {
      sendEmail: function (to, from, subject, text) {
        check([to, from, subject, text], [String]);
          to: to,
          from: from,
          subject: subject,
          text: text
      Meteor.startup(function () {    
        process.env.MAIL_URL = 'smtp://';          

If this behavior is intended, then please update documentation to reflect this.

- ensure that AppConfig callbacks are always called at least once
- don't start a new AppConfig Fiber every time you call Email.send

Fixes #1649.

Thanks. I'm taking a different approach to @Tarangp that fixes some related issues, so I'll keep this one open and close the PR.
