更改密碼出現錯誤訊息

[barsa]

我之前是用XP來架設學校的Life Type，但因為連線會有問題，所以請人安裝在Fedora c2，使用的版本是phpMyadmin 2.6.3， MySql是3.23.58，life type是1.0.3版
但因為我對Liunx非常不熟悉，所以狀況連連，大部分的問題可以在這裡找到解答，但目前最新遇到的狀況卻讓我不知道該如何是好，想請高手們解救一下
當有人想要更改密碼時，系統會出現以下訊息

Hi barsa:
請問你這台主機的smtp有開啟嗎?
從錯誤訊息看起來是無法從smtp送出變更密碼的確認信函。
你可以先�

我關了check_email_address_validity 跟email_service_enabled 就可以正常運作
所以我接下來要應該要設定smpt囉？
謝謝你的幫忙
如果我改好了
我在跟大家分享心得
謝謝
