In file bounce.php starting at Line 180 there is an logic to decode the Email

---SNIP---
  $transfer_encoding = '';
  if (preg_match('/Content-Transfer-Encoding: ([\w-]+)/i',$bounce["header"],$regs)) {
    $transfer_encoding = strtolower($regs[1]);
  } elseif (0 && preg_match('/Content-Type: multipart\/mixed;\s+boundary="([^"]+)"/im',$bounce['header'],$regs)) {
    ## @TODO, this needs more work, but probably easier to find a class that can
    ## split is all into it? parts
# print "BOUNDARY: ". $regs[1];
    $multi_part_boundary = $regs[1];
    $parts = explode($multi_part_boundary,$bounce["data"]);
    var_dump($parts);
    if (preg_match('/Content-Transfer-Encoding: ([\w-]+)/i',$bounce["data"],$regs)) {
 # var_dump($regs);
 # $transfer_encoding = strtolower($regs[1]);
    }
  }

  switch ($transfer_encoding) {
    case 'quoted-printable':
      $bounceBody = imap_qprint($bounce["data"]);break;
    case 'base64':
      $bounceBody = imap_base64($bounce['data']);break;
    case '7bit':
    case '8bit':
    default:
      $bounceBody = $bounce['data'];
  }
---END-SNIP---

so in the example above you get $transfer_encoding = base64;
the next step would decode the data-field using imap_base64 and this is wrong.

I suggest to use (if installed, otherwise fallback: the logic above or not)
http://pear.php.net/package/Mail_mimeDecode/


simple ex.:

function mimedecode($text) {
    require_once('Mail/mimeDecode.php');
    $params['include_bodies'] = true;
    $params['decode_bodies'] = false;
    $params['decode_headers'] = true;

    $decoder = new Mail_mimeDecode($text);
    $structure=$decoder->decode($params);
    

}

$decoded_email=mimedecode($bounce['header'].$bounce['data']);

ex. outout of $decoded_email obj.:
