smtp验证问题

[lizhilyz]

我的系统是AS5+vpopmail 5.4.25+mysql 5.0.22+cmd5checkpw-0.22+daemontools 0.76+ucspi-tcp-0.88+qmail-smtpd-auth-0.31+netqmail 1.06
我按配置后,用了网上很多种方法,都发现发邮件时,即使没有输入密码或密码不对,不管有没有勾选smtp验证,都能正常发邮件.
以下是我的telnet结果:
220 mail.test.net ESMTP
ehlo
250-mail.test.net
250-AUTH LOGIN CRAM-MD5 PLAIN
250-AUTH=LOGIN CRAM-MD5 PLAIN
250-PIPELINING
250 8BITMIME
以下是我的smtpd/run:
#!/bin/sh

QMAILDUID=`id -u vpopmail`
NOFILESGID=`id -g vpopmail`
MAXSMTPD=`cat /var/qmail/control/concurrencyincoming`
LOCAL=`head -1 /var/qmail/control/me`

if [ -z "$QMAILDUID" -o -z "$NOFILESGID" -o -z "$MAXSMTPD" -o -z "$LOCAL" ]; then
echo QMAILDUID, NOFILESGID, MAXSMTPD, or LOCAL is unset in
echo /var/qmail/supervise/qmail-smtpd/run
exit 1
fi

if [ ! -f /var/qmail/control/rcpthosts ]; then
echo "No /var/qmail/control/rcpthosts!"
echo "Refusing to start SMTP listener because it'll create an open relay"
exit 1
fi

exec /usr/local/bin/softlimit -m 200000000 \
/usr/local/bin/tcpserver -v -H -R -l mail.test.net -x /etc/tcp.smtp.cdb -c 100 \
-u "$QMAILDUID" -g "$NOFILESGID" 0 smtp /var/qmail/bin/qmail-smtpd mail.test.net /home/vpopmail/bin/vchkpw /bin/true \
/bin/cmd5checkpw /bin/true 2>&1

请高手帮忙解决问题,十分感激!!!!
