(offlineimap) 连接成功后邮件目录仍为空；强制方法没有任何区别

Question

我新安装了offlineimap，但第一次启动后我的邮件目录仍然是空的。此外，这里描述的方法http://offlineimap.org/doc/FAQ.html#can-i-force-offlineimap-to-sync-a-folder-right-now没有任何区别。我用的是最新的稳定版本。

我是不是忘记了什么？

我的.offlineimaprc：

remoterepository = mainRemote
synclabels = yes

[Repository mainLocal]

这个 .offlineimap 也没有什么区别
