easiForm
This is an easy form processing script that can be used for all your web forms as long as PHP 4.2.0 in running on the server where easiForm is located. The config file allows for many options on customisation but can be set up simply by adding the e-mail address and thanks page address to the config file then naming your form elements as per the naming convention in the easiForm README file. The actual easiForm is not readable and needs ioncube loaders to run but these are supplied with the script and should be uploaded to the server.
