How to make xampp php webpage send through sendmail

[rjo98]

Hi guys. first time trying out xampp, still learning. I have installed xampp, setup a php webpage that is a basic form to send email. But it doesn't appear to be sending. If i manually do a sendmail command from my server, the email sends, but xampp isn't using sendmail for some reason.

Am i missing a config or something to get the php form to use the sendmail installed on the server?
