PHP

Hi ,

I need help to solve this problem

This is the PHP coding

<?php
if((isset($HTTP_POST_VARS[“MM_insert”])) && ($HTTP_POST_VARS[“MM_insert”] == “form1”)){

$email_from = $_POST['email']; // Who the email is from
$email_subject = "New Reservation"; // The Subject of the email

$email_txt="Name: ".$_POST['name']."&lt;br&gt;";
$email_txt.="Contact: ".$_POST['contact']."&lt;br&gt;";
$email_txt.="Email: ".$_POST['email']."&lt;br&gt;&lt;br&gt;";

$email_txt.="Premises: ".$_POST['premises']."&lt;br&gt;";
$email_txt.="Bedroom Type: ".$_POST['bedrooms']."&lt;br&gt;";
$email_txt.="No Of Pax: ".$_POST['pax']."&lt;br&gt;";
$email_txt.="Check in date: ".$_POST['indate']."&lt;br&gt;";
$email_txt.="Check out Date: ".$_POST['outdate']."&lt;br&gt;&lt;br&gt;";

$email_txt.="Enquiry: ".$_POST['enquiry']."&lt;br&gt;";

$email_to = "retribution_2005@hotmail.com"; // Who the email is too

$headers = "From:".$email_from;

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "\

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

$email_message = "This is a multi-part message in MIME format.\


" .
"–{$mime_boundary}
" .
"Content-Type:text/html; charset=utf-8
" .
"Content-Transfer-Encoding: 7bit

" .
$email_txt . "

";

$ok = @mail($email_to, $email_subject, $email_message, $headers);		

header( 'Location: reservation.php?status=ok' ) ;

}
?>

The From: header has to be the email address the mail() is sending the email from, not the email address of the person who filled out the form.
