mail() header issue (again!)

[brentar]

I have an online application form.  I tested and wrote it on a windows machine.. once it switched to the "live" server which is Linux, it all went downhill.  There should always be 2 attachments sent out and any attachments the user added.  Only one comes through properly and the rest come up garbled.  The files upload to the server fine...  must be a header problem or a mime issue.  Any thoughts????  Thanks in advance.  I am guessing it is something silly between windows/linux.  I just can't find it.  I also told the company to switch so that both servers are the same!

Here are the main pieces of code.

 

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
$infoFile_type = "application/octet-stream";// File Type
$file = $_FILES['uploadedfile']['name'][0];
$files = fopen($fileatt,'rb');
$data = fread($files,filesize($fileatt));
fclose($files);

$data = chunk_split(base64_encode($data));

$email_from = "[email protected]"; // Who the email is from

$headers = "From: " . $email_from . "\n";

$headers .= "MIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"\n";

// $headers .= "From: ".$email_from;

$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";

$message .= "Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n";
$message .= "--{$mime_boundary}\n";
unset($data);
unset($file);
unset($fileatt);
unset($fileatt_type);
unset($fileatt_name);

Is there anything different between the type/content of the files that work and those that don't? Do plain text files work and binary don't?

It seems that the one file always goes through and the rest dont.  The content/type are the same for all 5.  I can add in all the code for all 5 if it helps
