Write your own. It'll only take a few lines of code.
As etully said, you already have the HTML form. Set the action attribute of the <form> tag to post back to the same page. Then, at the top of that page, add some PHP code that checks to see whether the page was loaded as the result of a form post. If so, it will retrieve the data that was entered into the form, and send it to whomever you like, using the mail() function.
This method is immune to the attack that's bitten you in the past, because the recipient's email address is stored in the PHP code on the server, rather than being provided by the client.
Your code might look something like this:
<?php
if ( $_POST["submit"] ) {
// we got here as the result of a form submission,
// so we'll process the form
// you might want to add some validation code here, to
// make sure the contents of the form are acceptable -
// or, use client-side Javascript to validate
// retrieve the form data
$name = $_POST["name"];
$color = $_POST["color"];
$fruit = $_POST["fruit"];
$animal = $_POST["animal"];
// build the email body
$email_body = "$name's favorite color is $favorite_color, his/her favorite fruit is $fruit, and his/her favorite animal is $animal!";
// send the email
mail( "recipient@somewhere.com", "My Favorite Things", $email_body );
// redirect to the confirmation page
header( "Location: confirmation_page.html" );
}
?>
