我无法使用javamail代码通过Outlook（hotmail account）配置发送邮件，但在gmail中工作正常

Question

我可以使用smtp.gmail.com主机发送邮件，但不能使用smtp.live.com，我也可以尝试使用465、25和587端口与主机进行通讯。

我的配置文件是

mail.smtp.host=smtp.live.com
mail.smtp.socketFactory.port=587
mail.smtp.socketFactory.class=javax.net.ssl.SSLSocketFactory
mail.smtp.auth=true
mail.smtp.port=587

我正在使用以下代码发送邮件。

Properties props = new Properties();
            try {                      props.load(UtilEmail.class.getResourceAsStream("properties/email.properties"));              
            } catch (IOException e1) {
                StringWriter stack = new StringWriter();
                e1.printStackTrace(new PrintWriter(stack));
                log.error(stack.toString());
            }

            final String user_name=<<my email address>>;
            final String password="<<my password>>";
            Session session = Session.getInstance(props,
                      new javax.mail.Authenticator() {
                        protected PasswordAuthentication getPasswordAuthentication() {
                            return new PasswordAuthentication(user_name,password);
                        }
                      });


            Message message = new MimeMessage(session);
             message.setFrom(new InternetAddress(user_name,title));
             message.addRecipient(Message.RecipientType.TO,new InternetAddress(to));
             message.setSubject(subject);
             message.setContent(body,"text/html");
             Transport.send(message);

而且我低于例外

我也曾经遇到过这个问题，当您尝试连接到没有SSL的安全加密通道时就会发生。 要解决此问题，您必须添加属性

mail.smtp.ssl.enable "true"

如果在此配置后出现证书问题，则还必须将服务器证书导入信任库中。
