POP3 class
This class provides an interface to the POP3 protocol with full support including APOP authentication. It provides both command based methods (eg _cmdUser() )as well as more abstract methods (eg getMessage() ).
Documentation is provided in the form of an example script which demonstrates all of the abstract methods
This class is available here. To use it successfully you will need to also have the Socket class, which you can obtain from PEAR. The POP3 class expects the Socket class to be in a folder called Net in your include path, so you may want/need to change the require_once() call at the top to suit your needs.
