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

Question

我正在尝试通过我使用实时域设置的自定义域发送电子邮件：https://domains.live.com。电子邮件本身有效，我可以使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。我想做的是通过 Java 和 JMail 发送电子邮件，这是我的代码（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();
    }
}

我替换我的用户名和密码，我收到以下消息：

Sending email!
javax.mail.MessagingException: Exception reading response;

注意：发件人邮箱与我的用户名相同！

我错过了什么？谢谢！

编辑：我已将道具更改为：

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");

同样的错误仍然显示..

编辑：我修好了。我使用 session.setDebug(true) 打开了调试，可以看到我没有电子邮件正文。所以我添加了 msg.setText("Content") 并且一切正常！

smtp.live.com 不侦听默认端口 25。它们似乎需要 TLS，因此您也必须在 javamail 中这样做。默认的 TLS 端口是 587，我已经确认您尝试连接的服务器在该端口上侦听。本文将向您展示如何设置端口：
