the professional edition 
  The Professional Edition of Endymion MailMan 
  is aimed at installations where an easily-installed and full-featured web-mail 
  solution is the goal. As the diagram illustrates, the Professional Edition downloads 
  messages from the specified POP3 server and stores them on the HTTP server, 
  so that they are archived even after they have disappeared from the POP3 server. 
                  Since the Professional Edition stores messages itself, it 
                    can offer more advanced functionality than the Standard Edition, 
                    such as organizing messages into folders. The Professional 
                    Edition also offers address books, user preferences including 
                    an outgoing signature, and the ability to check multiple external 
                    mail accounts. Endymion MailMan, Professional Edition is perfect 
                    for Internet service providers that would like to offer a 
                    full-featured web-based email interface for their existing 
                    users, companies that want to provide web-based email gateway 
                    to the outside world for employees, free email services and 
                    many other situations. 
                  The Professional Edition and the Standard Edition both share 
                    the same robust and time-tested interface and message rendering 
                    code that allows users to send and receive attachments, it 
                    allows you to fully customize the interface to merge with 
                    your existing web site, and allows you to customize the POP3 
                    and SMTP server names so that your users don't have to understand 
                    those details. If you would like to see the Professional Edition 
                    running on your own server, a fully-functional 30-day evaluation 
                    distribution is available online on our download
