 * Specific page to read a mailbox using the POP3 protocol, get the incoming

 * from the mailbox. In order to create tickets from emails received into
 * such an inbox, this page must be called at frequent intervals, since it
 * will process all the messages sitting in the inbox, then exit.
 * You can use a simple scheduled 'wget' command line script to call this page
 * from either a 'cron'' (Unix) or 'at' (Windows) command.
 * 
 * Use this page as an example and feel free to tailor it to your needs,
 * especially the default settings for the ticket (see below)
