python imaplib - 錯誤'意想不到的repsonse'

Question

嗨我突然遇到一個錯誤，使用imaplib上的一些代碼，以前工作正常。

import imaplib 
m = imaplib.IMAP4('myserver','port') 
m.login(r'username','password') 
m.select() 

給我的錯誤

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "/usr/lib/python2.7/imaplib.py", line 649, in select 
    typ, dat = self._simple_command(name, mailbox) 
    File "/usr/lib/python2.7/imaplib.py", line 1070, in _simple_command 
    return self._command_complete(name, self._command(name, *args)) 
    File "/usr/lib/python2.7/imaplib.py", line 899, in _command_complete 
    raise self.abort('command: %s => %s' % (name, val)) 
imaplib.abort: command: SELECT => unexpected response: '* 1520 EXISTS' 

我不知道這意味着什麼。否則電子郵件通過罰款，我使用davmail作爲服務器。

該程序完整保存附件在特定文件夾中的某個名稱。

我已經通過了它，它的確是m.select()這是它摔倒的地方。

直到最近，這個程序還是非常好的。

我在做什麼錯，我該如何解決？

活動的日誌如下

我現在的python-dev的

大衛提交下一個bug默裏表示，答覆是不符合RFC的

d在davmail SourceForge上

下的第二

davmail bug report

中號guessant說對IMAP保持活動是必要的。

我會記住這與發展更新..

看來，在RECENT響應的空間填充消息計數是什麼觸發此。我不清楚它是否應該在Python imaplib中或在您使用的IMAP服務器中歸類爲錯誤。我認爲imaplib應該對此強大，不管規範說什麼。也許你應該提交一份錯誤報告？ （如果你這樣做，請注意添加關於哪個服務器產生這個響應的細節，如果它是一個市場份額很大的商業產品，修復很重要，當然，如果它是你自己的簡單Python服務器，他們可能不關心。）
