SMTP setup 2 seperate exchange servers

Building off this topic

my 2 exchange servers in different sites, one being a child domain,
will both receive mail from postini which will route the correct users to the correct mail server eliminiating need for a front end server.

now I have to send mail.

currently i have one routeing group and one default smtp connector.

is that all i still need?
I see no need for the remote site to send mail through our smtp server here.. i would like them both to deliver there mail on there own.

my current one is for "*" namespace, and is the only bridge head listed (dont know what bridgehead is btw)

it is set to smarthost "localhost" as it relays through a little proxy/filter i have.

the remote site will not have this proxy.  I just want them both to deliver there mail seperatly when going outsie our domain.

What do i need to do with the connectors/routing groups?

I hope you will be able to follow what information i am going to provide now;

When exchange is placed in to different physical locations, its best advised that the message routing is configured to handle devices like switches / routers / firewall etc.

So the process that we need to follow is stated in detail below;

1. Under the default routing group, right click and select new routing group.
2. Rename it as something that that explains about the other site.
3. Get in to default (first) routing groups and drill down to "members".
4. You should find both the servers (local and remote).
5. Select the remote server and simply drag and drop it to the newly created routing group.
6. Now by design different routing groups cannot talk to each other if there is not a route defined, to achieve this a routing group connector needs to be created. Routing group conector (RGC) would be created mentioning local and remote bridghead (ideally in you case local and remote server from each routing group). Once this is established exchange would consider sending emails onle via this route. RGC is nothing but a route provided to exchange to send and reveice emails via a route marked by us. Please be advised that we need to create the RGC both ways.
7. When we edit attributes / create / delete objects in Exchange system manager, what we are baiscally doing is editing the active directory. What i ment by replication is all the changes that are being done requires active directory to replicate to all domain controllers.
8. Create 1 SMTP connector in each routing group with address space as "*" and scope as "routing group" and not "whole organization".
9. Configure the SMTP connector to use DNS or smarthost to send emails.

I hope the above explanation clears all your doubts.


Please follow steps that will make you life real easy.

1. Make additional routing group.
2. Move the remote server to the second routing group.
3. Create routing group connector to have internal mail flow between the servers.
4. Create SMTP conenctor with the required configuration (SMTP "*") and scope of the connector as routing group and select server.
5. Perfrom the same procedure for the server in the next routing group also.
6. Allow replication.
7. If you have latency in replication or issues routing emails, reboot both the exchange boxes once (this will force routing update).

After this is done both server's will have internal mailflow, plus indipendent external mailflow configured as you want.

Can i get a little more detail on

- Making an internal routing group connector?  

- enable replication.

Thanks for this info..

Ok trying now.. i blew my server up messing with DNS.. FULL SPEED AHEAD.
if i disapear for a few days agian,, it dint work  ;p
EricIT ManagerAuthor Commented:
your directions rocked.

What is a bridgehead btw?

local i have a smarthost which is my spam filter on port 25 (ex is on 24)
remote i have use DNS
Both use "default SMTP connector" for the coresponding server for the local bridghead in both the RGC and SMTP Connector.

is that right?

Hope its working.. cause local is production heap :)

Local bridghead is the local server and remote bridgehead is the remote server. when you try to add this it would show you the available Default virtual SMTP servers in the local site.

RGC configuration will not effect internet email so the smarthost on the SMTP connector is safe... Just be sure that you do not add the SMARTHOST on the default virtual SMTP server.

any email from remote host to local... when replieing to local to remote  is blank.!
i can type in it, send, it.. and it is completly blank everytime.
if i compose an email to smtp with FQDN  it works.

if i pull it out of the address book its blank :|

whats happening?

EricIT ManagerAuthor Commented:
And i had smarthost in both virtual and routing group connectors?  is that wrong?
EricIT ManagerAuthor Commented:
removed "smarthost: localhost" on virtual smtp server
same problem
EricIT ManagerAuthor Commented:
its been working.  thanks
