Multiple Domain Routing - Exchange 2003

I have question and think this is doable and trying to make sure I am on the
right path.

Large organization with many domains using Exchange 2003. Want to route
mail between domains to each 'bridgehead server' but outbound to an internal
outbound relay server.

Org A. www.my.domain.com
Org B. www.your.domain.com
Outbound Email Server-OES1

Org A. sends an email to someone on your.domain.com want mail to go to Org B
site.

Org A. sends an email to outside.world.com. Mail goes to OES1.

Is this doable with the SMTP routing connectors?

Hi there,

By Organization I gather you mean 'company' and not Exchange Org.

If you are a multi-tenant enviroment and have seperated companies onto their
own Exchange hardware within a single Exchange Organisation - you now want
to designate what servers are used if each customer decides to email one
another - is this correct?

If it is then you can use Routing Group Connectors, with an Org wide SMTP
connector for delivery out to the Internet.

If i've mis-interpreted or read you wrong - please clarify.

Oliver, yes Oganization in this case can mean company. however we are gov't
so we have lots of companies / orgs that use exchange but have different
domains. IE xyz.xx.gov, abc.xx.gov, 123.xx.gov. And these orgs do not want
to combine into one or two domains or trusted domains.

However I prefer the email get routed directly to each org instead of going
to the internet and coming back in. Since they use our network to
communicate.

Aha - so they are seperate - if you really want to then, you can create SMTP
connectors, or if all use a common Smarthost, you can configure routing
there.

Does that make sense?

In regards to Bharats post - are you sharing the same smtp namespace between
the Orgs? If so you will need to configure this also. Can you clarify.

Oliver and Bharat thanks.

Again there are many organizations within the state so yes we probably share
some namespaces.

IE: 123.state.gov
abc.state.gov

So they many be *.state.gov but we have others with
123.state.xx.us

and similar.

I think we configure that if an email on 123.state.gov is going to
123.state.xx.us or abc.state.gov then I can configure smtp connectors that
would basically say route to the appropriate server. Else if not this then
send to Internet.

I thought this was doable but there have been some disagreements and I
wanted to confirm it was. Seems to be so.

Glad we could be of help.
