This is the PHP version of my secure form mailer script. This script has a wide range of features including: an easy to use dynamic form generation system (any number of fields, in any order), multiple recipients, multiple file attachments, optional auto reply feature, an image verification system, numerous security features (including protection against email header injection), a message template system, multiple languages, and too many other things to list. This script was designed to be easy to use, while still being extremely flexible. If you just want a simple contact form, you can set one up with just a few clicks. For those of you who need something a bit more advanced, you can completely customize script plugin to fit your needs - whether it is 5 fields or 500. A WordPress plugin version is also available. ReCaptcha support has also been added, as well as support for storing the data in a delimited file.

This script has been tested on our servers and it works perfectly.
