1. decodeHeader 函式主導郵件編碼的解碼，$utfencode=true 表示郵件為 utf8 編碼，$htmlsave=true 表示保留 html 格式，$decide=false 表示決定不必解碼。

   [root@mail squirrelmail-1.4.8]# grep ^function.*decodeHeader -R /var/www/squirrelmail/
   /var/www/squirrelmail/functions/mime.php:function decodeHeader ($string, $utfencode=true,$htmlsave=true,$decide=false) {  //dywang debug this function
   

2. 為得到更正確的郵件編碼的解碼，郵件顯示時呼叫 decodeHeader 函式時，傳入 $utfencode=false,$htmlsave=false,$decide=true 三個參數。
