Upload to email script

[scrupul0us]

Right now I have a script that will allow a webuser to upload a file to my webserver if it meets certain conditions... however, id like to email that file somewhere instead of uploading it to the server using the mail() function but have no idea how to do attachments stuff....
heres my functional upload script:

<center><h3>Upload Drawings</h3><br  />
<table align="left" id="uploadform" cellpadding="2" cellspacing="2">
<form name="upload" ENCTYPE="multipart/form-data" method="post">
<tr>
<td colspan="2">
<?php
//These are for if u wanna spit out a link to the file after
//shiznuts is complete --commented out--
/*$site_name = $_SERVER['HTTP_HOST'];
$url_dir = "http://".$_SERVER['HTTP_HOST'].dirname($_SERVER['PHP_SELF']);
$url_this =  "http://".$_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF'];*/

$upload_dir = "upload_files/";
$upload_url = $url_dir."/upload_files/";
$message ="";

//create upload_files directory if not exist
//If it does not work, create on your own and change permission.
if (!is_dir("upload_files")) {
	die ("upload_files directory doesn't exist");
}

if ($_FILES['userfile']) {
	$message = do_upload($upload_dir, $upload_url);
}
else {
	$message  = "Please Select a Valid File.<br  />";
	$message .= "Valid Filetypes Are: <b>.dwg</b>, <b>.zip</b><br  />";
	$message .= "Maximum Filesize is: <b>10MB (megabytes)</b>";
}

print $message;

function do_upload($upload_dir, $upload_url) {
	$password  = $_REQUEST['password'];
	$user_ip   = $_SERVER['REMOTE_ADDR'];
	$temp_name = $_FILES['userfile']['tmp_name'];

	$result    = $_FILES['userfile']['error'];
	$file_url  = $upload_url.$file_name;
	$file_path = $upload_dir.$file_name;

$file_ext      = substr($file_name, -3);
$allowed_types = array('dwg','zip');
$accepted_pw   = 'cad2005';

//Pasword Check
if ($password =="")

	return $message;

{
	$message = "<b>Sorry, That Filetype is Invalid.</b>";
	return $message;
}

$result  =  move_uploaded_file($temp_name, $file_path);

$message = ($result)?"Success!" :
