IMAP文件夾接收郵件兩次

我正在嘗試使用Java郵件API來開發電子郵件偵聽器。我收到兩封同樣的電子郵件，情況不會每次都發生;隨機發生。IMAP文件夾接收郵件兩次

下面的代碼是用來做IMAP連接

try { 
      isConnecting.set(true); 
      createSession(); 
      LOGGER.warn("session created "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
      store = session.getStore("imap"); 
      if(store==null){ 
       LOGGER.warn("store is null return from here"+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
       return; 
      } 
      store.connect(imapServerAddress, imapLoginId, imapPasswrd); 
      LOGGER.warn("Connecting successful "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
      folder = store.getFolder(folderName); 
      LOGGER.warn("Folder creating "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
      if (timer == null) { 
       timer = new HashedWheelTimer(1, TimeUnit.SECONDS); 
      } 
      if (idleManager == null) { 
       idleManager = new IdleManager(session, es); 
      } 
      if (folder == null || !folder.exists()) { 
       LOGGER.warn("invalid folder exit from here "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
       System.out.println("Invalid folder"); 
       return; 
      } 
      synchronized (folder) { 
       LOGGER.warn("Folder sync "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
       folder.addConnectionListener(this); 
       folder.open(Folder.READ_WRITE); 
       folder.addMessageCountListener(this); 

       System.out.println("message count listener added"); 
       LOGGER.warn("message count listner added "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
       if (folder instanceof IMAPFolder) { 
        IMAPFolder f = (IMAPFolder) folder; 
        System.out.println("enter idle"); 
        LOGGER.warn("Idle condition "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
        idleManager.watch(f); 
        setIsConnected(true); 
        LOGGER.warn("Folder.watch "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
        DbUtil.updateMediaStream(getIdentifier(), true); 
        isConnecting.set(false); 
        connectionAttempt.set(0); 
        LOGGER.warn("Db updated "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
        System.out.println("idle done"); 
        scheduleTask(); 
        LOGGER.warn("Scheduler starts "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
       } 

      } 

      System.out.println(new Date() 
        + "================================== connect() end"); 
      LOGGER.warn("____________________END connecting "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd); 
     } catch (Exception fex) { 

       if (connectionAttempt.get() >= 3) { 
        LOGGER.error("Reconnection Failed", fex); 
        connectionAttempt.set(0); 
        throw new IllegalStateException(
          "Error while connecting mediaStream", fex); 
       } 
       LOGGER.error("Reconnecting mediastream attempt " 
         + connectionAttempt.get(), fex); 
       connectionAttempt.incrementAndGet(); 
       closeFolderAndStore(); 
       connect(); 

     }

電子郵件這裏收到的「公共無效messagesAdded（MessageCountEvent EV）」 方法調用兩次

@Override 
    public void messagesAdded(MessageCountEvent ev) { 
     Message[] msgs = ev.getMessages(); 
     System.out.println("Got " + msgs.length + " new messages"); 
     LOGGER.info("New message received {}" ,msgs.length); 
     // Just dump out the new messages 

     for (int i = 0; i < msgs.length; i++) { 

      try { 

       // msgs[i].writeTo(System.out); 

        System.out.println("-----"); 
        System.out.println("Message >>" + msgs[i].getMessageNumber() 
          + ":"); 
        LOGGER.info("Email Received >>> {}" , msgs[i].getMessageNumber()); 
        processEmail(msgs[i]); 


      } catch (Exception ioex) { 
       LOGGER.error("messagesAdded:getmessagenumber", ioex); 
       ioex.printStackTrace(); 
      } 
     } 
     try { 
      synchronized (folder) { 
       if (folder != null && idleManager != null) { 
        idleManager.watch(folder); 
       } 
      } 
     } catch (Exception e) { 
      LOGGER.error("messagesAdded:watch", e); 
      e.printStackTrace(); 
     } 
    }

這是在郵箱消息號466。服務器宣佈新的消息：

* 3 RECENT 
    * 466 EXISTS

您處理消息：

A16 FETCH 466 (ENVELOPE INTERNALDATE RFC822.SIZE) 
    ...

你等待新的消息，並且服務器會告訴你：

* 466 EXPUNGE 
    * 466 EXISTS

這意味着消息編號466已從郵箱中完全刪除，郵箱中有一個新的郵件號碼466。 JavaMail的通知您新的訊息號466很顯然，這是完全一樣的刪除消息號466

我不知道爲什麼服務器這樣做。它看起來像服務器中的一個bug。 請將其報告給Microsoft。

您可能想要檢查正在處理的消息的IMAP UID。新消息466絕對必須具有不同的UID。如果沒有，那是服務器中更嚴重的錯誤。

您還可以檢查郵件的Message-ID，以確保你以前沒有見過該消息。如果所有的錯誤情況都是這樣的，你可能只需要保留一條消息的歷史記錄。但需要注意的是，雖然郵件ID的目的是唯一的，通常是獨特的，不同於IMAP的UID沒有保證，他們是獨特的，甚至它們的存在的。
