Question

我正在尝试使用Javamail Api连接到IMAP。我可以通过此代码成功连接到Gmail，但无法连接到我的大学ID。

public class MailConnection {
    Folder inbox;

public MailConnection() throws MessagingException{
    Properties props = System.getProperties();
    props.setProperty("mail.store.protocol", "imap");
     try{
         Session session = Session.getInstance(props, null);
         Store store = session.getStore("imap");
         store.connect("mailbox.xyz.com", "emailId@xyz.com", "password");
         System.out.println(store);

         inbox = store.getFolder("Inbox");
         System.out.println("No of Unread Messages : " + inbox.getUnreadMessageCount());
     }
     catch (NoSuchProviderException e){
            e.printStackTrace();
            System.exit(1);
     }
}

当我使用我的Uni id时，我收到以下错误消息 -

javax.mail.MessagingException: * BYE ;
  nested exception is:
    com.sun.mail.iap.ConnectionException: * BYE

我不知道这里出了什么问题。这个BYE意味着什么？如何解决这个问题？
