sending pdf attachment in email in Aol email

Question

I am sending a pdf attachment within an email and am having an issue when trying to be opened in Aol mail. The attachment showing like on email abc.pdf (< 1 KB).The attachment says:

Adobe Reader could not open'abc.pdf' because it is either not a supported file type or because the file has been damaged(for example, it was sent as an email attachement and wasn't correctly decoded).

Here is my code:

include("walljs/mpdf/mpdf.php");
$mpdf=new mPDF();   
$mpdf->ignore_invalid_utf8 = true;
$stylesheet = file_get_contents('appstyle_pdf.css');
$mpdf->WriteHTML($stylesheet,1);
$mpdf->WriteHTML($output);
$comname = preg_replace("/[^A-Za-z0-9]/","",$_POST['company']); 
$name = $dirname.str_replace(" ","-",$comname)."_".$time_stamp.".pdf";        
$mpdf->Output($name,"F");   

$file = $name;
$crlf = "\n";
$filename = basename($file);
$file_size = filesize($file);
$content = chunk_split(base64_encode(file_get_contents($file))); 
$uid = md5(uniqid(time()));
$header = "From: [email protected] \r\n"
      ."MIME-Version: 1.0\r\n"
      ."Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n"
      ."This is a multi-part message in MIME format.\r\n" 
      ."--".$uid."\r\n"
      ."Content-type:text/plain; charset=iso-8859-1\r\n"
      ."Content-Transfer-Encoding: 7bit\r\n\r\n"
      .$message." 
      ".$companyinfo."\r\n\r\n"
      ."--".$uid."\r\n"
      ."Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"
      ."Content-Transfer-Encoding: base64\r\n"
      ."Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n"
      .$content."\r\n\r\n"
      ."--".$uid."--";

Any Suggestions please.

Any debugging done? Such as looking at the mail source, smtp filtering headers, checking the attachment with pdfinfo etc? Nobody's going to help with that gruesome manual mime construction copy pasta; consider PhpMailer/SwiftMailer. — mario

Try to define your headers in he string $headers like that :

    'Content-Type: application/pdf';
    'Content-Disposition: inline; filename="'.$filename.'"';
        'Cache-Control: private, max-age=0, must-revalidate';
    'Pragma: public';
