/**
* A simple web-mailer based on Zend_Mail_Storage classes.
*
* This simple mailer demonstrates the most important features of the mail reading classes. You can
* use the test mbox and maildir files or a Pop3 or Imap server. It's meant to be run in a web enviroment
* and CLI is not supported. Copy the files to a directory in your webroot and make sure the Zend Framework
* is in your include path (including incubator!).
*
* SSL and TLS are supported by Zend_Mail_Storage_[Pop3|Imap], but not shown here). You'd need to add
* 'ssl' => 'SSL'
* or
* 'ssl' => 'TLS'
* if you want to use ssl support.
*
* Because of problems with Windows filenames (maildir needs : in filenames) the maildir folder is in a tar.
* Untar maildir.tar in maildir/ to test maildir support (won't work on Windows).
*
* The structure of the class is very simple. Every method named show...() output HTML, run() inits mail storage
* after login and calls a show method, everything else inits and checks variables and mail storage handler.
