imapsync：NO APPEND 錯誤保存消息

我正在使用 imapsync 1.525 將郵件遷移到 ubuntu 12.04 上的 zarafa 7.1.4。對於相當多的消息（大約 32000 條），我收到以下錯誤：

其他消息已正常遷移。附件目錄有 zarafa 的權限，大約 150G 大，所以我假設 zarafa 成功地在那裡儲存了附件。文件系統上也有足夠的空間。

Zarafa 網關告訴我（日誌級別 6）：

文件夾名稱以空格結尾（“收件箱/我的文件夾”）似乎很奇怪，但這似乎不是問題，其他消息已成功遷移到該文件夾。

我想知道“$Forwarded”標誌，這似乎很奇怪，因為所有其他標誌都以反斜杠開頭。但是在測試帳戶中，此標誌遷移得很好。

關於如何解決這個問題的任何想法？

事實證明，我達到了 zarafa 配額。我用 Thunderbird 看了之後才發現（Gilles LAMIRAL 在 imapsync maillinglist 上建議 - 謝謝）。在那裡我看到了配額。所以在zarafa提高配額後，問題就解決了。

如果不是這樣，請升級到最後一個 Mail::IMAPClient perl 模組。

什麼給出了 df 命令？

   df /tmp
   df -i /tmp

/tmp 可以被 inode 或空格填滿。
