Linux Mail Server Setup and Howto Guide

I followed the post: Postfix Active Directory/LDAP Integration.

My ldap-users.cf configuration has:

server_host = serverwin1.redlinux.org
search_base = dc=redlinux,dc=org
version = 3
query_filter = (&(objectclass=person)(mail=%s))
result_attribute = administrador
result_format = %s/Maildir/
bind = yes
bind_dn = administrador@redlinux.org
bind_pw = 123456

Main.cf has:

mydestination = $myhostname, localhost.$mydomain, localhost

virtual_mailbox_domains = $mydomain
virtual_mailbox_base = /home/vmail/
virtual_mailbox_maps = ldap:/etc/postfix/ldap-users.cf
virtual_uid_maps = static:504
virtual_gid_maps = static:504

I restart MailScanner, because i have Postfix+Dovecot+MailScanner+Spamassassin+Clamav.

and i have an active directory server(windows server 2003)

But when i test postfix with telnet:

[root@mail postfix]# telnet localhost smtp
Trying 127.0.0.1…
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 mail.redlinux.org ESMTP Postfix
mail from: lordonez@redlinux.org
250 2.1.0 Ok
rcpt to: mnarro@redlinux.org
550 5.1.1 <mnarro@redlinux.org>: Recipient address rejected: User unknown in virtual mailbox table

Suggestions? help me please.

Thanks a lot!
