44502 formmail script set up

Hello, This is a very simple project for a reliable coder. I need formmail script set up and configured on my web site. I have two (2) forms on my web site that need to be configured to work with the formmail script. I would like any suggestions you may have on the best way to set this up so the forms cannot be misused. I have attached a zip with the newest version of the formmail script.
