Question

Properties props = new Properties();
    props.put("mail.smtp.host", "smtp.office365.com");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.auth", "true");
    //props.put("mail.smtp.socketFactory.class","javax.net.ssl.SSLSocketFactory");//As discussed but does not work if the leave
    props.put("mail.smtp.port", "587");



    Session session = Session.getInstance(props,
        new javax.mail.Authenticator() {
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("mail@domi.cl","paswwd");
            }
        });

    try {

        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress("mail@domi.cl"));

        message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("mail@domi.cl"));
        message.setSubject("Resumen envio masivo");
        message.setText(mensajeMail);

        Transport.send(message);

        System.out.println("Done");

    } catch (MessagingException e) {
        throw new RuntimeException(e);
    }

下面是StackTrace：

Could not connect to SMTP host: smtp.office365.com, port: 587;
  nested exception is:
    java.net.ConnectException: Connection refused: connect
javax.faces.el.EvaluationException: java.lang.RuntimeException: javax.mail.MessagingException: Could not connect to SMTP host: smtp.office365.com, port: 587;
  nested exception is:
    java.net.ConnectException: Connection refused: connect

Answer 1

该异常意味着您无法连接到服务器smtp.office365.com上的端口587。使用telnet验证：

telnet smtp.office365.com 587

这可能导致您无法在您所在地工作的原因是：

Java中配置错误的代理设置

如果它不起作用并且您在公司网络中，那么很可能是导致问题的防火墙。还要检查密码和电子邮件是否正确。

也许它适用于TLS。你应该试一试。

请检查您域的SMTP端口号或尝试我的代码。
