Problems with user email information in contact form

I have a contact form for my cart. I just recently noticed a problem when testing by sending an email to me using the contact form and one of my email addresses not associated with the cart. I receive the email okay at the email associated with the cart, but it shows as being sent by the username associated with my web hosting username, not the sender of the email entered in the email section of the form. I don't know how to configure the contact form to send the correct email address from the person who sent it. I'm using opencart Version 3.0.3.6. Can someone provide some insight on how to fix this? Thanks.

Look at the raw email headers. What is the Reply-To header set to?
