Postfix + sasl = não funciona

Galera, preciso muito de ajuda. Administradores... se puderem ajudem por favor!!

Estou com problema para enviar email. Tenho postfix + sasl. Abaixo minhas confs

/etc/pam.d/smtp
auth required pam_mysql.so user=postfix passwd=nga host=localhost db=postfix table=mailbox usercolumn=username passwdcolumn=password crypt=1
account required pam_mysql.so user=postfix passwd=nga host=localhost db=postfix table=mailbox usercolumn=username passwdcolumn=password crypt=1

/etc/postfix/sasl/smtpd.conf
pwcheck_method: saslauthd

/etc/default/saslauthd
START=yes
DESC="SASL Authentication Daemon"
NAME="saslauthd"
MECHANISMS="pam"
MECH_OPTIONS=""
THREADS=5
OPTIONS="-c -m /var/run/saslauthd -r"

tail -f /var/log/auth.log (ao tentar logar smtp no outlook express)
