Contact Form Reply to Email Address

Hi Kriesi
When I receive an email from the standard contact form in Enfold and reply to it, it replies to the standard email address used throughout my setup.
How can I get the reply to address to automatically be the sender’s email address (The person’s email address who submitted the query through the contact form, who filled in their email address.)
Currently, I have set up in my functions.php for email –

/* enter the full email address you want displayed */
/* from http://miloguide.com/filter-hooks/wp_mail_from/ */
function xyz_filter_wp_mail_from($email){
return " (Email address hidden if logged out) ";
}
add_filter("wp_mail_from", "xyz_filter_wp_mail_from");

/* enter the full name you want displayed alongside the email address */
/* from http://miloguide.com/filter-hooks/wp_mail_from_name/ */
function xyz_filter_wp_mail_from_name($from_name){
return "My website name";
}
add_filter("wp_mail_from_name", "xyz_filter_wp_mail_from_name");

Thank you for your time
