Question

我提出了一个需要发送电子邮件的申请。它以前工作过，但是当我今天要运行它时，它抛出java.net.UnknownHostException: smtp.outlook.com。它过去常常工作，在outlook配置上做了一些改变吗？

这是我的代码：

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smpt.host", "smtp.outlook.com");
    props.put("mail.smtp.port", "587");
    props.put("mail.smtp.starttls.enable", "true");

    Session session = Session.getInstance(props, null);
    try {
        transport = session.getTransport("smtp");
        try {
            transport.connect("smtp.outlook.com", username, wachtwoord);
        } catch (MessagingException ex) {
            ex.printStackTrace();
        }
    } catch (NoSuchProviderException ex) {
        ex.printStackTrace();
    }

它会抛出以下错误：

javax.mail.MessagingException: Unknown SMTP host: smtp.outlook.com;
  nested exception is:

非常感谢任何帮助，
