dovecot: Aug 21 08:38:54 Info: POP3(agenzia): Disconnected: Logged out 
top=0/0, retr=0/0, del=0/21, size=217625
in this check  the client have not download the message

dovecot: Aug 21 08:40:20 Info: pop3-login: Login: user=<agenzia>, 
method=PLAIN, rip=213.203.182.90, lip=91.102.48.12
dovecot: Aug 21 08:40:20 Info: POP3(agenzia): Disconnected: Logged out 
top=0/0, retr=1/2962, del=0/21, size=217625
