Problems with Postfix and smtp auth

[Sergio Belkin]

In Ubuntu 7.04 I have problems with Postfix+Dovecot+Sasl


I got these messages from /var/log/mail.log

This is my /etc/default/saslauthd
START=yes

PARAMS="-m /var/spool/postfix/var/run/saslauthd -r"

MECHANISMS="shadow"



My /etc/postfix/sasl/smtpd.conf:
saslauthd_path: /var/run/saslauthd/mux
pwcheck_method: saslauthd
mech_list: plain login


This is my main.cf (I included only smtpdauth relative to be shorther)
#Seccion agregada por Sergio Belkin para lograr autenticacion mediante SASL
#Habilito autenticacion del servidor mediante SASL
smtpd_sasl_auth_enable = yes
# Permite el relay desde redes confiables y aquellos usuarios autenticados
smtpd_recipient_restrictions =  permit_sasl_authenticated,
permit_mynetworks, reject_unauth_destination
# Para recibir el nombre del usuario autenticado a partir del encabezado
smtpd_sasl_authenticated_header = yes
# Para evitar problemas con clientes viejos de Microsoft
broken_sasl_auth_clients = yes
# Le digo que voy a usar SASL con Dovecot
smtpd_sasl_type = dovecot
#smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous
smtpd_sasl_local_domain =


If I try with telnet:

telnet 10.1.1.253 25
Trying 10.1.1.253...
Connected to 10.1.1.253.
Escape character is '^]'.
Connection closed by foreign host.

I can't see where is the problem :( could you help me?

Thanks in advance!!
