Contact form always says "Sent" – even when not

There’s a bug in the contact form. When you send it always returns TRUE for the email send even when it’s not sent.

$mail = wp_mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }

    if ($emailSent == true) {

$mail is set to the result of wp_mail which may be false, but the internal variable $emailSent is always true. $emailSent should be set to the value of $mail, probably.

There is also no error handling in place for a failed send.
