One of the simplest things you can do is to send the results of the form to an email address. There will be no formatting, and there is a risk of getting spammed, but it is useful for testing, etc.:
<form method="post" action="mailto:firstname.lastname@example.org">
You could also consider using DreamHost's own implementation of FormMail, although I have no personal experience of using it.
