我在阅读 pop3 邮件时遇到问题

我的代码很简单..

Properties objServerProp = new Properties();
objServerProp.setProperty("mail.transport.protocol", "pop3");
objServerProp.setProperty("mail.host", "xxx.xx-ip.org");
objServerProp.put("imap.mail.port", "110");
objServerProp.put("imap.mail.auth", "true");

Session  objSession = Session.getDefaultInstance(objServerProp, null);
Store instStore = objSession.getStore("pop3");
instStore.connect("xxx.xx-ip.org", Integer.valueOf(110), "id", "pwd");
Folder  objFolder = instStore.getFolder("inbox");
objFolder.open(Folder.READ_WRITE);
int count = objFolder.getMessageCount();

 Message objMessage = objFolder.getMessage(1);
 System.out.println("objMessage is :: "+objMessage);
 System.out.println("  message contenttype :: " + objMessage.getContentType());

当我在消息对象上调用任何方法（例如 :getContentType() ）时，我遇到了异常，，，

并且消息对象很好

objMessage is :: com.sun.mail.pop3.POP3Message@37d8d2

例外如下..

javax.mail.MessagingException: error loading POP3 headers;
  nested exception is:
    java.io.IOException: Unexpected response:

如 JavaMail FAQ 中所述，打开会话调试。协议跟踪将向您显示意外响应是什么。您还应该查看com.sun.mail.pop3 包 javadocs 中描述的属性，其中一些可能有助于解决服务器中的错误。
