Connect Two exchange servers - 31.May2010 10:41:11 AM

This forum helped me to install the exchange server. Now i stuck at somewhere. I installed exchange 2003 on Windows server 2003 on 2 diffrent domains abc.com and xyz.com. I want to connect my two exchanger servers so anyone can send mail to each other

My first domain configuration is
Domain name - abc.com
FQDN Names - mail.abc.com
ip - 192.168.1.1
gateway - 192.168.1.1
dns - 192.168.1.1

I setup forward and reverse lookup zones for FQDN name and succesfully resolves the hostname to ip and ip to hostname
----------------------------------------------------------------------------------
Second domain config is
Domain name - xyz.com
FQDN Names - mail.xyz.com
ip - 192.168.1.2
gateway - 192.168.1.2
dns - 192.168.1.2

Dns configured to resolve host names

-------------------------------------------------------------------------------
I made smtp connector and address space on both side
In abc
SMTP - Forward all mails to [192.168.1.2]
Brighead server: MAIL
Address Space : @xyz.com

In xyz
SMTP - Forward all mails to [192.168.1.1]
Brighead server : MAIL.
Address space : @abc.com

Now if user@abc.com sends mail to user@xyz then the user@abc receives the mail from itself
I m confused

Since you've created two separate domains (and presumably they are in separate Exchange Organizations), you have two choices.  Either allow the messages to be routed to the Internet and back in, or create SMTP connectors to deliver the messages directly.

Routing via the Internet means both domains have to be registered and have MX records that point to public IP addresses.  Since the addresses you list are all private addresses, I'm assuming that this has not been done.

Routing via SMTP connectors in this case means each Exchange Organization has a way to point traffic directly to an address.  That means each Org has a connector which names the other SMTP domain in its address space, and the opposite private IP address as its Smarthost address.

Thanx uemurad.
I configured the SMTP on both ends. I entered xyz.com in the address space of abc.com also the private ip of abc.com and entered abc.com in the adress space of xyz.com also the private ip of xyz.com

Do i need to configure anything more ? or this is fine ?  do i need to make trusts in between diff domains ?

If you are only trying to send messages back and forth, that should all you need to do.

Trusts are an Active Directory function, not messaging.  Trusts are needed if one AD forest needs to look at the other for any particular reason.  Just as you don't need to have any trust for you to send messages to Yahoo or Gmail, you don't need any to have the two SMTP domains send messages back and forth.

 I still dont figure out where is the problem.
The abc.com sends mail only to abc.com users and xyz sends mail only to xyz.com users

1. DNS is configured properly on both sides
2. I made SMTP connectors and the opposite ip in the smart host
3 .Add the Opposite domain name is the address space in the SMTP connector
     eg. ABC.COM has xyz.com in its address space and XYZ.COM has    abc.com in its address space.
Where i missed ?

Did you create/edit any Recipient Policy on either side naming the other domain?  It sounds like you want to treat the two SMTP domains as separate entities, so you don't want to include them in the Recipient Policies.

Next, use Message Tracking to see what Exchange is trying to do with a message headed to the other domain.

Next, enable and search the SMTP logs to see what is happening with Exchange-to-Exchange communication.

Thank you so much uemurad. You saved me.
The problem was i edited the receiptent policy and included the SMTP Domain of other domain. Now every user can send mail to diffrent domains.

uemurad what is use of receptent policy ? In what scenario we need to edit that policy ?

The Recipient Policy serves three major purposes. First, it stamps AD objects with Email addresses according to a format formula. Second, it can be used to define Mailbox Management parameters (to report on and/or automatically purge messages based on size or age). Third, and what applies to your situation, is that it tells Exchange which SMTP domain names for which the Organization is responsible.

If you add a second SMTP domain to the policy then tell Exchange it is responsible, any messages addressed to that other domain will stay internal to the Organization as opposed to routing outside the Organization.

Since you have two separate Exchange Organizations, you need to look at the Recipient Policies in each.
