$privatekey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXX";

$resp = recaptcha_check_answer ($privatekey,
                                $_SERVER["REMOTE_ADDR"],
                                $_POST["recaptcha_challenge_field"],

if ($resp->is_valid) {
    ?>success<?
}
else
{
    die ("The reCAPTCHA wasn't entered correctly. Go back and try it again." .
       "(reCAPTCHA said: " . $resp->error . ")");
}

You should put your code to send the email near the end of your code inside of:

if ($resp->is_valid) {
    ?>success<?
}

Replace ?>success<? with whatever you're using to send the email.
