Thanx for your tips.  I should have let you know that 
"mime_content_type" is custom in my case as my instance of PHP does not 
have that function (I'm using 4.3.2); simple one-liner that does an exec 
on "file -bi " on the file wrapped around escapeshellarg().

Here is the updated function that now seems to work:

[PHP]
// ORIGINAL FUNCTION FOUND AT 
http://www.php.net/manual/en/function.mail.php#41681 WITH cc AND bcc 
MODIFICATIONS BY PHIL POWELL 6/10/2004
function mail_attach($to, $subject, $message, $from, $files = false, 
$lb="\n", $cc = '', $bcc = '') {
 /*----------------------------------------------------------------------------------------------
     $to Recipient
     $from Sender (like "email at domain.com" or "Name <email at domain.com>")
     $subject Subject
     $message Content
     $files hash-array of files to attach
     $lb is linebreak characters... some mailers need \r\n, others need \n
-------------------------------------------------------------------------------------------------*/
 global $phpVersionInt;
 $mime_boundary = "<<<:" . md5(uniqid(mt_rand(), 1));
 $header = 'From: '. $from;
 if ($cc) $header .= $lb . "Cc: $cc";
 if ($bcc && (int)$phpVersionInt > 430) $header .= $lb . "Bcc: $bcc";
 if (is_array($files)) {
  $header.= $lb;
  $header.= "MIME-Version: 1.0".$lb;
  $header.= "Content-Type: multipart/mixed;".$lb;
  $header.= " boundary=\"".$mime_boundary."\"".$lb;
  $content = "This is a multi-part message in MIME format.".$lb.$lb;
  $content.= "--".$mime_boundary.$lb;
  $content.= "Content-Type: text/plain; charset=\"iso-8859-1\"".$lb;
  $content.= "Content-Transfer-Encoding: 7bit".$lb.$lb;
 }
 $content.= $message.$lb;
 if (is_array($files)) {
  $content.= "--".$mime_boundary.$lb;
  foreach($files as $filename => $filelocation) {
   if(is_readable($filelocation) && is_file($filelocation)) {
     $fileID = @fopen($filelocation, 'r');
     $data = @fread($fileID, filesize($filelocation));
     @fclose($fileID);
     $data = chunk_split(base64_encode($data));
       $content.= "Content-Disposition: attachment;".$lb;
       $content.= 'Content-Type: ' . mime_content_type($filelocation) . ';';
       $content.= " name=\"".$filename."\"".$lb;
       $content.= "Content-Transfer-Encoding: base64".$lb.$lb;
       $content.= $data.$lb;
       $content.= "--".$mime_boundary.$lb;
   }
  }
 }
 if (mail($to, $subject, $content, $header)) return true;
 return false;
}
[/PHP]

Thanx for your help!
