I will please to help you to review th FAQ but I still ha ve an issue:

When I try to send a mail from a outside address to a mailbox list in the iRedMail LDAP database ("dovecot mode") I get this :

connect from smtp21.xxxxxx.com[8x.1x.2xx.xx]
NOQUEUE: reject: RCPT from smtp21.xxxxxx.com[8x.1x.2xx.xx]: 450 4.7.1 : Recipient address rejected: Policy Rejection- Please try later.; from= to= proto=ESMTP helo=
disconnect from smtp21.xxxxxx.com[8x.1x.2xx.xx]

The question is :

Where can I set the Policy Rejection ??
Can I set direct transport mode and local delivery mode at the same time ??

Thanks

if you don't want to create user accounts in iredmail, you have to config this domain as backup mx, but you can't reject spams before relay to exchange server.

if you want to host this domain as backup mx, set 'domainBackupMX=yes' & 'mtaTransport=smtp:xxx:25' in this domain, and comment 'relay_recipient_maps' in postfix main.cf.

I confirm with this configuration :
dn: domainName=test.com,o=domains,dc=iredmail,dc=org
mtaTransport: smtp:Your_Exchange_Server:25

I get :
550 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table;

And receive a MAILER-DEAMON undelivery mail

Ok, so I don't have to create all accounts.

just create the domain in the LDAP database and set 'mtaTransport=smtp:XXX:25'.

Postfix will directly send all the mails to my exchange

I'm confused.

You want to receive mails, and then relay them to your exchange server, right?

If so, you don't need to use backup mx.
You can host your domain as a normal mail domain, but relay all mails to exchange server with 'mtaTransport=smtp:XXX:25' in domain LDAP data.

I get this for mailbox witch doesn't exist:
NOQUEUE: reject: RCPT from ey-out-2122.google.com[74.125.78.25]: 550 5.1.1 : Recipient address rejected: User unknown in virtual mailbox table; from= to= proto=ESMTP helo=

But reffering to this in (relay_domains = /etc/postfix/ldap_relay_domains.cf)
query_filter = (&(objectClass=mailDomain)(domainName=%s)(domainBackupMX=yes)(accountStatus=active)(enabledService=mail))
result_attribute= domainName

To work I think that domainBackupMX must to be set to "yes"

Re: Transport per-domain (backup MX)

null@example.com (ZhangHuangbin) — Tue, 13 Oct 2009 13:19:25 +0000

Does it work without 'domainBackupMX'?

Thanks to your quick reply.

I set :
domainBackupMX = yes
dn: domainName=test.com,o=domains,dc=iredmail,dc=org
mtaTransport: smtp:Exchange_Server:25
add the IP address of Exchange_Server to mynetworks in /etc/postfix/main.cf

I try with a exist mailbox i get this :
to=, relay=dovecot, delay=0.09, delays=0.01/0.03/0/0.05, dsn=2.0.0, status=sent (delivered via dovecot service)
But it's don't arrive in the xxxx@Exchange_Server

If I try to send a mail to a mailbox which not apear in the ldap database I get this:
Recipient address rejected: User unknown in relay recipient table; from= to= proto=ESMTP helo=

How can I get the job done ???

Thanks
