Exchange 2003 share smtp domain

Hi,
I have 2 exchange 2003 server in two differents organisation. I would like to share smtp domain between a short period. each organisation have it own smtp domain and i would like to share both on the 2 exchange server (server1 and server2). server1 have smtp domain forest1.local  and server2 have forest2.local. I would like server1 to be able to receive mails for forest2.local and server2 forest1.local. For that i configure recepient policy on each server to say forest1.local and forest2.local are not autoritative domain. For each server i say unresolved recepient to be forward to each other. And i configure a connector to relay domain to the other server.
user Test1.forest1.local is located on server1 and Test2.forest2.local on forest2
My problem is i am not able receive mail locally and on server2 with domain forest1.local

Do you understant what i mean?

Thanks

You need to setup shared SMTP Name Space as per the following article to allow both servers to receive mail for each other and to route it if the relevant mailbox is not found on the receiving server:

One of the servers needs to be authoritative for one or both of the domains.  Currently you are showing neither domain as authoritative for either domain.
I would set server 1 as authoritative for techno and server 2 authoritative for toto and then test it again.  It should be okay after you have done this.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

Sorry - the above would read better if I had said the following:
You have to have a server being authoritative for both domains, either one for one domain and one for the other or both on one.

Ok server1 is authoritative for techno and server2 authoritative for toto
result:

-mail from external to domain techno.fr on server 1 => OK
-mail from external to domain techno.fr on server 2 => ok
-mail from external to domain toto.fr on server 2 => ok
-mail from external to domain toto.fr on server 1 => Ok
-mail from server1 to user techno.fr locate on server2 => Don't work
-mail from server2 to user toto.fr locate on server1 => Don't work
-mail from server1 to user techno.fr locate on server1 => ok
-mail from server2 to user toto.fr locate on server2 => Ok

Have you followed the section titled "SMTP Domains that are not local for your Exchange Organization" in the link I provided?
You need to setup a new SMTP connector on both servers (figure 2 in the article I linked) that uses a Smarthost to send mail to the other server and is allowed to relay.
You also need to forward all mail with unresolved recipients to the following smarthost as per figure 3 in the article I linked.

So to recap, you need to do the following:
Server 1
  • set as authoritative for techno
  • setup a recipient policy that is not authoritative for toto domain
  • setup smtp connector using server 2 as smarthost and allow relay to the domain
  • setup forwarding of unresolved mail to server 2 under SMTP Virtual Server
Server 2
  • set as authoritative for toto
  • setup a recipient policy that is not authoritative for techno domain
  • setup smtp connector using server 1 as smarthost and allow relay to the domain
  • setup forwarding of unresolved mail to server 1 under SMTP Virtual Server

setup smtp connector using server 2 as smarthost and allow relay to the domain  => i had address space  techno.fr on connector

setup smtp connector using server 1 as smarthost and allow relay to the domain =>  i had address space  toto.fr on connector

Alan HardistyCo-OwnerCommented:
On the SMTP Connector on Server 1, you need to add the address space toto and allow relay and add Server 2 as the smarthost
On the SMTP Connector on Server 2, you need to add the address space techno and allow relay and add Server 1 as the smarthost
