set /etc/dovecot/conf.d/10-auth.conf
# modifiche dovecot+postfix+ad
#auth_username_format = %Lu
*auth_username_format = %n*
auth_debug = yes
ssl = no
first_valid_uid = 500
last_valid_uid = 500
first_valid_gid = 500
last_valid_gid = 500


and execute the following telnet session
[root at posta ~]# telnet localhost 25
Trying ::1...
telnet: connect to address ::1: Connection refused
