兄弟們幫我看看，「telnet localhost 110 」 出錯！

兄弟們幫我看看，「telnet localhost 110 」 出錯！

這一個星期都在搞postfix，對於小弟來說第一次配置郵件伺服器的確有點難度，現在還沒解決，但我沒有放棄，我一直在努力。
下面是我遇到的問題，telnet localhost 25  驗證可以通過，
就是在telnet localhost 110  的時候，出現以下錯誤：

-ERR Maildir invalid (no 'cur' directory)
Connection closed by foreign host.

還一個問題是：
我在用postfixadmin建立域名和用戶郵箱的時候，在/var/mailbox/下面就是不出來目錄，
小弟也查閱了相關資料，也沒找出原因？

兄弟們幫忙看看，謝謝！
