postfix安装后配置maildrop的问题 (自己解决了!)

我家老婆最美丽

RH AS4系统.
只安装了Postfix, 在初步了解了main.cf的内容后. 只做了最基本的配置,现在可以发送内部外部的mail了.
建了一个Virtual Domain, 手动加了几个用户,创建了Virtual_mailbox_maps文件,可以收发了,用户的目录在/mail/newtest会自动建立,在"user1/Maildir"目录下会有new,cur等目录.
具体配置如下
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
home_mailbox = Maildir/
html_directory = no
inet_interfaces = all
local_recipient_maps = unix:passwd.byname $alias_maps
mail_owner = postfix
mail_spool_directory = /mail/test

mailq_path = /usr/bin/mailq
manpage_directory = /usr/local/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = test.com
myhostname = mail.test.com
mynetworks = 192.168.1.0/24, 127.0.0.0/8
mynetworks_style = subnet
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = no
relay_domains = $mydestination
relayhost = mail.internet.com
sample_directory = /etc/postfix
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
smtpd_banner = $myhostname ESMTP $mail_name
unknown_local_recipient_reject_code = 550
virtual_gid_maps = static:5000
virtual_mailbox_base = /mail/newtest
virtual_mailbox_domains = newtest.com
virtual_mailbox_maps = hash:/etc/postfix/virtual_mailbox
virtual_alias_maps = hash:/etc/postfix/virtual

virtual_transport = maildrop
virtual_uid_maps = static:5000

现在的问题是,我安装了Maildrop之后,如果在main.cf中加一句:
virtual_transport = maildrop
则邮件无法发送到用户目录中,/var/log/maillog的信息是:

Aug  4 17:04:38 qmail postfix/pipe[9106]: 83BE23AC063: to=<user1@newtest.com>, relay=maildrop, delay=0.01, delays=0/0/0/0.01, dsn=5.1.1, status=bounced (user unknown. Command output: Invalid user specified. )

请帮忙看看是什么问题? "User unknown",那么这个Maildrop到哪里去找用户信息的呢?

没有用virtual_transport = maildrop这一句.

根据 Postfix.org网站上的文档,用了
mailbox_command = /usr/bin/maildrop

就可以了.
