Answer 1

First make headers

$headers = "From: $from\r\nReply-to: $email";

Than fix calling of mail function to be

mail ($to, $subject, $body, $headers)

Didn't tried it from times when it was PHP 4 but it will probably work as you expected...

Addition: I just checked on php.net... go to this url http://php.net/manual/en/function.mail.php and check "Example #2 Sending mail with extra headers."
