How can I make my website send email after checking captcha : <p>I'm trying to setup a service for my friend where he will post an email request from his site to mine with html form tag and then my site will request a captcha check it's valid then send him the email but I'm not sure how to </p>

<p>I tried some online options but I can't find anything that will request the captcha then redirect to send the message check it's valid then send it</p>
