关于QMAIL+VPOPMAIL+MYSQL的POP3认证问题

[hblfknight]

我使用以上环境建一个邮件系统，使用WEBMAIL很正常，但是使用OUTLOOK EXPRESS时发现不能认证，情况如下：
1、对于RC.LOCAL文件
#Start smtp service
echo "Starting th smtp service ......"
QMAILDUID='/usr/bin/id -u qmaild'
NOFILESGID='/usr/bin/id -g qmaild'
/usr/local/bin/tcpserver -v -l 0 -H -R -x /home/vpopmail/etc/tcp.smtp.cdb \
-c 20 -u "$QMAILDUID" -g "$NODILESGID" 0 smtp\
/var/qmail/bin/qmail-smtpd 2>&1>/dev/null &
# start the pop3 service
echo "Starting the pop3 service......"
/usr/local/bin/tcpserver -l 0 -v -H -R 0 pop-3 \
/var/qmail/bin/qmail-popup 192.168.0.100 \
/home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir 2>&1 >/dev/null &

2、对于日志文件MAILLOG：（baohong用户肯定存在，使用WEBMAIL正常）
maillog about POP3

Jul 24 00:29:00 gigalinux vpopmail[1404]: vchkpw: vpopmail user not found baohong@:192.168.0.240
Jul 24 00:29:04 gigalinux vpopmail[1407]: vchkpw: vpopmail user not found baohong@:192.168.0.240

3、关于MYSQL中的VPOPMAIL库：
MYSQL
pw_name pw_domain pw_passwd pw_uid pw_gid pw_gecos pw_dir pw_shell pw_clear_passwd
baohong 192.168.0.100 $1$ISaNf$CUzc7ws11pCQih7KCTo7Z1 0 0 baohong /home/vpopmail/domains/192.168.0.100/baohong NOQUOTA 123 Edit Delete

到现在走投无路了，不知道问题出在什么地方！
