Hi, list.

I'm having problems with transport when message is sent to not
existent users.

My structure:

internet
|
(1) Antivirus
|
(2) Internal Smtp
| | |
(3) Backends

User database: openldap.

main.cf SERVER 1 (antivirus):

transport_maps = ldap:/etc/postfix/ldap-transport.cf

-> This consult the ldap server for the backend server where is the Maildir:
query_filter =
(&(&(objectClass=CourierMailAccount)(|(mail=%u)(maildrop=%u)))(|(account Status=enabled)(accountStatus=forward)))
result_attribute = mailhost
result_filter = smtp:%s

main.cf SERVER2 (internal smtp):
transport_maps = hash:/etc/postfix/transport

transport of server 2:
* smtp:[server1.domain.com]
# because all e-mails need to check for virus, internal and external,
correct ?

Existents accounts are ok, this is working, but when account not exists,
the sender give the following error:

relay=none, delay=0, status=bounced (mail for domain.com loops back to
myself)

Any help will be appreciated.
