使用jmail java从自定义实时domian outlook com发送电子邮件

Question

我正在尝试通过我的自定义域名发送一封电子邮件，该域名是我使用活动域名https://domains.live.com设置的。电子邮件本身是有效的，我可以用我的自定义域用户名和密码登录outlook.com，并发送和接收邮件。我想要做的是通过Java和JMail发送电子邮件，下面是我的代码(来自这里：http://www.oracle.com/technetwork/java/javamail/faq-135477.html#outlook)：

public static void sendEmail() throws MessagingException{
    System.out.println("Sending email!");

    String host = "smtp.live.com"; // using this or smtp-mail.outlook.com has the same outcome.
    String username = "username";
    String password = "password";

    Properties props = new Properties();
    props.put("mail.smtp.starttls.enable", "true");

    Session session = Session.getInstance(props);
    MimeMessage msg = new MimeMessage(session);
    msg.setSubject("Test Subject");
    msg.setFrom(new InternetAddress("fromemail"));
    msg.addRecipient(Message.RecipientType.TO, new InternetAddress("toemail")); 

    Transport t = session.getTransport("smtp");

    try {
        t.connect(host, username, password);
        t.sendMessage(msg, msg.getAllRecipients());
    } finally {
        t.close();
    }
}

我代入我的用户名和密码，得到以下消息：

Sending email!

注意:发件人电子邮件与我的用户名相同！

我遗漏了什么？谢谢!

编辑:我已经将我的道具修改为：

Properties props = new Properties();
props.put("mail.smtp.auth", "true");  // If you need to authenticate
props.put("mail.smtp.host", host);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.starttls.enable", "true");

仍然显示相同的错误..

编辑:我修复了它。我打开了debug using session.setDebug(true)，可以看到我没有电子邮件正文。所以我添加了msg.setText("Content")，这一切都起作用了！

smtp.live.com不侦听端口25，该端口是默认端口。看起来他们需要TLS，所以你也得用javamail来做。默认的TLS端口是587，我已经确认您尝试连接的服务器正在侦听该端口。本文将向您介绍如何设置端口：
