Postfix con sasl

[Marco Salgado A.]

Hola, escribo ya que no he podido con esta mescla, he hecho todo segun 
la documentacion de postfix y he buscado en otras partes y no me 
funciona la autenticacion para enviar correo desde fuera de la red.

Un postconf -n entrega:
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = yes
biff = no
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
config_directory = /etc/postfix
content_filter = smtp-amavis:[localhost]:10024
daemon_directory = /usr/lib/postfix
mailbox_command =
mailbox_size_limit = 0
mydestination = xxx.cl, www.xxx.cl, localhost.xxx.cl, localhost
mydomain = xxx.cl
myhostname = xxx.cl
mynetworks = 127.0.0.0/8, 192.168.0.0/24, 169.254.165.0/24
myorigin = /etc/mailname
recipient_delimiter = +
relayhost =
setgid_group = postdrop
smtpd_banner = $myhostname ESMTP
smtpd_recipient_restrictions = 
permit_sasl_authenticated,permit_mynetworks,check_relay_domains,reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_sender_restrictions = 
permit_sasl_authenticated,permit_mynetworks,check_relay_domains,reject_unauth_destination

Tambien tendo en /etc/postfix/sasl/smtpd.conf tengo:
mech_list:      cram-md5 digest-md5 plain
pwcheck_method: shadow

Y los log me dicen algo como:
postfix/smtpd[6154]: warning: SASL authentication problem: unable to 
open Berkeley db /etc/sasldb2: No such file or directory
postfix/smtpd[6154]: warning: SASL authentication problem: unable to

postfix/smtpd[6154]: warning: SASL authentication problem: unknown 
password verifier
postfix/smtpd[6154]: warning: SASL authentication failure: Password 
verification failed

El archivo /etc/sasl2 existe y esta con permisos 644. Realmente ya no se 
que hacer asique alguna ayuda seria muy bien recivida. Saludos!
