Cannot send email with Wakanda Server 1.1.3

When I attempt to send an email via Wakanda Server, using the following code, an error occurs:

var mail = require('waf-mail/mail');
var message = new mail.Mail();
message.subject = "Here the subject of the email";
message.from = "me@mydomain.com";
message.to = 'user@somedomain.com';
message.setBody("This is a test message");

mail.send({
    address: 'mail.mydomain.com',
    port: 587,
    isSSL: true,
    username: 'MY-USERNAME',
    password: 'MY-PASSWORD',
    domain: 'mydomain.com'
}, message);

When running in debug mode, during mail.send the error occurs at the following line:

socket = tls.connect(port, address, connectCallback);

When debugging, I cannot step into this function call and the error occurs when attempting to do so.

The docs say that mail.send should return a status object, but that doesn't happen here. Adding a try/catch to the mail.send call produces this Error object in the catch:

Error = {
    error: [{
        componentSignature: "xbox"
        errCode: 5
        message: ""}],
    messages: [""]
}

Wakanda Server 1.1.3

MacOS 10.11.6

I am not using gmail to send the email.

Make sure you have the correct address and port in the mail.send properties. you have to search the correct smtp settings for the mail you are using. for gmail i succed sending emails using the following :

var mail = require('waf-mail/mail'); 
var message = new mail.Mail();
message.subject = "Test";
message.from = "me@gmail.com";
message.to = ['me@gmail.com' , 'user@wakanda.io'];
message.setBody("This is a test message");
mail.send({
    address: 'smtp.gmail.com', 
    port: 465,
    isSSL: true,
    username: 'username', 
    password: 'password', 
    domain: 'gmail.com'
}, message);
