You could use reference check and cookies or

http://www.php.net/manual/en/reserved.variables.php
http://www.php.net/manual/en/function.setcookie.php


make a extra page which redirects the user to the page that shows the data

form_page -> redirect&sendmail_page -> displaypage

this way when they refresh, they only refresh the displaypage
