Prevent Post Office Protocol access

If you do not want anyone to use Post Office Protocol (POP) to access your iSeries™ server, you should prevent the POP server from running.

If you do not plan to use POP at all, do not configure it on your iSeries server (or allow anyone else to configure it).

• Prevent Post Office Protocol from starting when TCP/IP starts
  You might need to use Post Office Protocol (POP) occasionally, but want to limit the amount of access users have the POP server.
• Prevent access to Post Office Protocol ports
  To secure your Post Office Protocol (POP) server from unknown applications, you might want to prevent access to POP ports.
