QNAP TS-451 Xeams ERROR " You are running out of disk space on /tmp"

祝大家新年快樂

小弟有個Qnap TS-451, 把把 TS-451用來作Mail server,
但安裝了Xeams (要有POP及IMAP)後, 出現以下問題,不知在哪裡改才行.


You are running out of disk space on /tmp

Automatic alert from Xeams - DO NOT reply
--------------------------------------------

You are running out of disk space. Details:

Machine name: TS-451
Path: /tmp
Space left: 61.73 MB


謝謝!
