使用java通过Exchange服务器发邮件时，在内网可以正常发送，但是不能发往互联网邮箱，错误代码如下：

严重: Servlet.service() for servlet jspthrew exception

程序代码如下：

public void addMail() throws AddressException, MessagingException{
              Properties props = System.getProperties();
              props.put("mail.smtp.host", "10.2.32.145");
              props.put("mail.transport.protocol", "smtp");
          props.put("mail.smtp.auth", "true");  
          Email_AutherticatorBean auth = new Email_AutherticatorBean("zhq.hao@cbhb.com.cn","Password02!");

for(int i=0;i<1;i++){

Session mailSession = Session.getInstance(props, auth);
                      Message msg =  new MimeMessage(mailSession);
                      //发件人邮箱
                      msg.setFrom(new InternetAddress("han.huang@cbhb.com.cn"));

//收件人邮箱地址
                      InternetAddress[] address = null;
                      address = InternetAddress.parse("test_bohai@163.com",false);
                      msg.setRecipients( Message.RecipientType.TO, address);

String temp = "内容内容";

msg.setSubject("主题haha"+(i+1));                              
                      msg.setSentDate(newDate());                           
                      msg.setText(temp);

//                     Transport.send(msg);
                      SMTPTransport t = (SMTPTransport) mailSession.getTransport("smtp");
                      try {
                              if (true)
                                      t.connect("10.2.32.145", "cbhb/zhq.hao","Password02!");
                              else
                                      t.connect();
                              t.sendMessage(msg, msg.getAllRecipients());
                      } finally {
                              t.close();
                      }
              }

}
经过分析后，发现代码需要简单修改，修改后如下：

其中最重要的问题是，我的邮件服务器上为了配合其他应用开启了匿名访问，然而这段程序中用的是验证身份的方式，在通过邮件服务器时，服务器认为是匿名发送，导致不能发往外网。我把代码中smtp用的端口25改为587就好使了。还有一个方法是专门为这个java发送服务器开启中继也可以，一定是只针对这个java服务器的IP而不是针对所有的中继。
