Fixing the "contact us" email

When someone uses the "contact us" form, the site email is set as the sender, so If you want to reply, you have to copy the sender's email, then start a new message, rather then just hitting the reply button.  Is there a way to fix it so whoever is sending the email, they're email will show as the sender, making it as easy as hitting the reply button?

Great point.  I wish I had a solution.
