Create the POP3 Server Publishing Rule
Remote access to the Exchange Server POP3 service allows users located away from the
office to download their mail from the Exchange Server to virtually any e-mail client
application. Users must provide a user name and password when they connect to the POP3
service. They download e-mail into their e-mail client application after sending their
credentials. These user credentials are sent in clear text. In a production environment, you
would require an SSL-secured POP3 connection so that user name and password are not
easily accessible to Internet intruders.
