igenus(webmail)不能上传和显示中文附件问题的解决

qmail-vpopmail-courier-imap-qmail-clamav-scanner-igenus安装完成后,webmail(igenus)无法上传和显示中文附件的名称:
  原因:basename 的作用在于过滤文件名中的路径信息，但是由于该函数固有的缺陷，在 unix 环境下面，对 windows/dos 的路径信息没有起作用，故而该函数在此没有实际意义。可以去掉，办法是自己写一个类似的函数来替代。
  解决:1.编辑 "include/send_fun.php" ,改写basename函数
         function formatAttachmentHeader($inFileLocation){
         $outAttachmentHeader = "";
         //--get content type based on file extension
         $contentType = $this->getContentType($inFileLocation);
      //add by leera begin--    #下面部分为添加的部分
         $str=$inFileLocation;
         $tmpArray=split("/",$str);
         $sFileName=$tmpArray[count($tmpArray)-1];
         $s_inFileLocation=$sFileName;
      //add by leera --end      #添加到这里
     
         if($this->Encoding=='quoted-printable')
         $filename = encode_mime($s_inFileLocation,$this->Encoding,$this->Charset);    #把下面一行改为这行
         //$filename = encode_mime(basename($inFileLocation),$this->Encoding,$this->Charset);
         else $filename = encode_mime($s_inFileLocation,'base64',$this->Charset);      #把下面一行改为这行
         // else $filename = encode_mime(basename($inFileLocation),'base64',$this->Charset);
========================================================================
      2.编辑mime.php,去掉basename,并且强制以下载的方式浏览附件
         $get_File = rawurldecode(trim($_GET['File']));  #把下面一行改为这行

         //$get_File = rawurldecode(basename(trim($_GET['File'])));
         $get_MimeType = $_GET['MimeType'];
         $get_Size = $_GET['Size'];
         $get_Cmd = $_GET['Cmd'];
        
         if (false){                                            #把下面一行改为这行
         //if ($get_Cmd=="Show"){
         $file = $File;
         $filename = "$CFG_TEMP/$SG_DOMAIN/$SG_USERNAME/$get_File";
         ($FD_ATTACH = fopen($filename,"r")) || die("Error open !filename");
         if(substr_count($file,'.pif') || substr_count($file,'.exe') || substr_count($file,'.scr') ||
         substr_count($file,'.com') || substr_count($file,'.bat') ){
         $buff = "<Script>\n";
         $buff .= "alert('警告：该邮件中可能携带有病毒程序！')\n";
         $buff .= "</Script>";
         echo $buff;
         exit();
         }
        
         if (true){                                    #把下面一行改为这行
         //if ($get_Cmd=="Download"){
         $filename = "$CFG_TEMP/$SG_DOMAIN/$SG_USERNAME/$get_File";
         ($FD_ATTACH = fopen($filename,"r")) || die("Error open !filename");
         header("Content-type: $get_MimeType; name=\"$get_File\"\n");
         header("Accept-Ranges: bytes\n");
