【问题描述】：

我可以使用 smtp.gmail.com 主机发送邮件，但不能使用 smtp.live.com 我也尝试使用主机的 465、25 和 587 端口。

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);

我得到以下异常

    ERROR: util.UtilEmail - javax.mail.MessagingException: Could not connect to SMTP host: smtp.live.com, port: 587;

【解决方案1】：

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

mail.smtp.ssl.enable "true"

如果您在此配置后遇到证书问题，那么您还必须在您的信任库中导入服务器证书。
