hi guys,
i'm trying to configure Postfix to allow only authenticated users to send emails.
But still users without authentication can send emails too. What did i wrong. i'll try to post my main.cf

Code:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = no

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# SASL SUPPORT FOR CLIENTS
# The following options set parameters needed by Postfix to enable 
# Cyrus-SASL support for authentication of mail clients. 
# 
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
broken_sasl_auth_clients = yes

smtpd_recipient_restrictions = 
   permit_sasl_authenticated, 
   permit_mynetworks, 
   check_relay_domains

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = mail.myfirstdomain.lt, localhost.localdomain, localhost, myfirstdomain.lt
relayhost = 
mynetworks = 127.0.0.0/8, 192.168.1.0/24
mailbox_size_limit = 50000000
recipient_delimiter = +
inet_protocols = all
home_mailbox = Maildir/
mailbox_command = 
virtual_alias_domains = myfirstdomain.lt myseconddomain.ru mythirddomain.lt 
virtual_alias_maps = hash:/etc/postfix/virtual
canonical_maps = hash:/etc/postfix/canonical
I added this part of code in my main.cf
Code:
# SASL SUPPORT FOR CLIENTS
# The following options set parameters needed by Postfix to enable 
# Cyrus-SASL support for authentication of mail clients. 
# 
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain = $myhostname
broken_sasl_auth_clients = yes

smtpd_recipient_restrictions = 
   permit_sasl_authenticated, 
   permit_mynetworks, 
   check_relay_domains
when i try to telnet i see aded these two new lines:

Code:
 
220 myfirstdomain.lt ESMTP Postfix (Ubuntu)
ehlo myfirstdomain.lt
250-myfirstdomain.lt
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-AUTH PLAIN DIGEST-MD5 LOGIN NTLM CRAM-MD5
250-AUTH=PLAIN DIGEST-MD5 LOGIN NTLM CRAM-MD5
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
But still users can login and send mail without secure password authentication.

What is wrong ?

Thanx for your answers
