First the php part:

My provider blocked the "from" header to receive mails from external websites so i arranged it a bit to send the mail from my domain and i read the customer email with the "name" tag

<?php
if(isset($_POST['email'])) {

// EDIT THE 2 LINES BELOW AS REQUIRED
$email_to = " This e-mail address is being protected from spambots. You need JavaScript enabled to view it ";
$email_subject = "your_desired_subject";


function died($error) {
// your error code can go here
echo "We are very sorry, but there were error(s) found with the form your submitted. ";

echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}

// validation expected data exists
if(!isset($_POST['name']) ||

!isset($_POST['email']) ||

!isset($_POST['comments'])) {
died('We are sorry, but there appears to be a problem with the form your submitted.');
}

$first_name = $_POST['email']; // required
$customer_name =  $_POST['name'];

$email_from = " This e-mail address is being protected from spambots. You need JavaScript enabled to view it "; // required   (here u must provide a email adress from your domain)

$comments = $_POST['comments']; // required

$error_message = "";
$email_exp = "^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$";
if(!eregi($email_exp,$email_from)) {
$error_message .= 'The Email Address you entered does not appear to be valid.<br />';
}
$string_exp = "^[a-z .'-]+$";
if(!eregi($string_exp,$name)) {
$error_message .= 'The Name you entered does not appear to be valid.<br />';
}

if(strlen($comments) < 2) {
$error_message .= 'Your message do not appear to be valid.<br />';
}

if(strlen($error_message) > 0) {
died($error_message);
}
$email_message = "Form details below.\n\n";

function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}

$email_message .= "Email: ".clean_string($first_name)."\n";
$email_message .= "Name: ".clean_string($customer_name)."\n";
$email_message .= "Internal Email: ".clean_string($email_from)."\n";
$email_message .= "Comments: ".clean_string($comments)."\n";


// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$first_name."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers); 
?>
