Best PHP form to email processing script?

I'm looking for a PHP form to email processing script...a free one that is NOT hosted (I want the script myself on my own server). Which is the best one?

 

You can use PHP's IMAP class (http://www.devarticles.com/c/a/PHP/Create-Your-Own-Mail-Script-With-PHP-and-IMAP/) to easily connect to an email and retrieve the messages. You can also pipe emails to a php script. Thwe pipe method is a bit more efficient, but the IMAP method is a little easier to control.

 

No, I do not want to check my email using PHP. I want a simple html form that will be converted to an email. Similar to formmail except in PHP.

 

Here's one I've used in the past: http://www.stuffbysarah.net/2008/03/19/secure-php-contact-form/
