Problem sending mail with attachment

Hi,

I am trying to send an email with an attachment via the phpmail function on a "Zend Core for i5"-System:

Code: Select all

<?php
 
  $Dateiname = "./dokument_templates/symbollegende.pdf";
  $Dateinameanhang = "symbollegende.pdf";
 
  $to="target@abc.de";
  $subject="Test Attachement";
  $headers = "From: test@abc.de";
  $message = "Test Test Test Test";
  
  // Read the file to be attached ('rb' = read binary)
  $file = fopen($Dateiname,'rb');
  $data = fread($file,filesize($Dateiname));
  fclose($file);
 
  // Generate a boundary string
  $semi_rand = md5(time());
  $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
  
  // Add the headers for a file attachment
  $headers .= "\nMIME-Version: 1.0\n" .
              "Content-Type: multipart/mixed;\n" .
              " boundary=\"{$mime_boundary}\"";
 
  // Add a multipart boundary above the plain message
  $message = "This is a multi-part message in MIME format.\n\n" .
             "--{$mime_boundary}\n" .
             "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
             "Content-Transfer-Encoding: 7bit\n\n" .
             $message . "\n\n";
 
  // Base64 encode the file data
  $data = chunk_split(base64_encode($data));
 
  // Add file attachment to the message
  $message .= "--{$mime_boundary}\n" .
              "Content-Type: application/pdf;\n" .
              " name=\"{$Dateinameanhang}\"\n" .
              "Content-Disposition: attachment;\n" .
              " filename=\"{$Dateinameanhang}\"\n" .
              "Content-Transfer-Encoding: base64\n\n" .
              $data . "\n\n" .
              "--{$mime_boundary}--\n";
 
 
// Send the message
$ok = @mail($to, $subject, $message, $headers);
 
?>
With a Thunderbird email client it is doing as expected, but when getting the mail with MS-Outlook (via Exchange) the mail displays wrong. The attachment is coded as text in the message.....
Any suggestions what went wrong?
