php Contact Form on website and reply-to email

I have a PHP Contact form on a site I am hosing on our mediatemple grid server that was made with Rapidweaver. It works well except that the email it generates to our info@ourdomain.com is sent as serveradmin@o开发者_StackOverflow社区urdomain.com. I think the server is just using the trash/blackhole address. Any way to adjust my php or better yet, the server settings, to send the mail as the reply-to address that the user fills out on the contact form itself?

Why? Well Google hosts the email for this domain and I wanted to use their canned responses as an auto-responder. The problem of course, is that the auto-response goes to serveradmin@ourdomain.com and not the user's email address that he filled in on the form.

Thank you for the help!

You can add headers to your mail

<?php
$to      = 'nobody@example.com';
$subject = 'the subject';
$message = 'hello';
$headers = 'From: webmaster@example.com' . "\r\n" .
    'Reply-To: webmaster@example.com' . "\r\n" .
    'X-Mailer: PHP/' . phpversion();

mail($to, $subject, $message, $headers);
?>
