代码
public ReadInboxTask() throws MessagingException {
prop = System.getProperties();
//prop.put("mail.store.protocol", PropertyFactory.MAIL_STORE_PROTOCOL);
//prop.put("mail.imap.host", PropertyFactory.MAIL_IMAP_HOST);
prop.put("mail.store.protocol", "imap");
prop.put("mail.imap.host", "imap.qq.com");
System.out.println("监听邮件任务创建...");
}


Session session = Session.getInstance(prop);
IMAPStore store = (IMAPStore) session.getStore("imap"); //使用imap会话机制，连接服务器
//store.connect(PropertyFactory.USER, PropertyFactory.PASSWORD);
store.connect("********@qq.com", "ghsxiwxfzjghdjib");--密码是qq邮箱登录第三方客户端时，生成的授权码，不行，我换成qq邮箱的密码也不行
IMAPFolder folder = (IMAPFolder) store.getFolder("INBOX");//收件箱
folder.open(Folder.READ_WRITE);

你的目的是监控别人邮箱么？还是什么。我或许懂一点
