A POP3 server MAY have an inactivity auto logout timer. Such a timer MUST be of at least 10 minutes'
duration. The receipt of any command from the client during that interval should suffice to reset the auto
logout timer. When the timer expires, the session does NOT enter the UPDATE state--the server should
close the TCP connection without removing any messages or sending any response to the client.
