sendmail smtp auth

Hello everybody!

I am trying to disable open relay, that's why I want to configure
smtp_auth in sendmail 8.13 with login plain

if I execute this command
sendmail -d0.1 -bv root | grep SASL
I get
NETUNIX NEWDB NIS PIPELINING SASLv2 SCANF SOCKETMAP STARTTLS

in sendmail.mc I added
define(`confAUTH_OPTIONS', `A')dnl
define(`confAUTH_MECHANISMS', `LOGIN PLAIN')dnl
TRUST_AUTH_MECH(`LOGIN PLAIN')dnl

in /usr/lib/sasl2/
I modified Sendmail.conf and now there is only one line:
pwcheck_method:shadow

if I telnet localhost 25
ehlo localhost
I get
250-AUTH LOGIN PLAIN

but when I try to connect from windows live mail I can't authenticate, please help
