Hi guys

I have 1 Exchange 2003 server servicing 2 domains, I would like for the one mail domain (@abc.com) to rout all outgoing mail via another relay server ( this server does mail branding only applicable to that domain). And for the other domain(@def.com) to route via the default setup(direct DNS delivery)

What I have done is setup a SMTP connector to forward all mail form abc.com to the relay but it doesn?t exclude the @def.com domain. Here is my configuration.

General ? Forward all mails through connecter [ip]
Address space ? SMTP abc.com entire organization

I have set the connector to accept mail from all in the abc.com domain and to reject def.com domain

Please help !!!

The SMTP connecter is still forwarding mail from both domains @abc.com + @def.com.

Let me clarify

I would like to route all mail outgoing from @abc.com through the connector and all outgoing mail from @def.com through the default exchange setup (DNS direct delivery). When the connecter is setup it does not differentiate between the two domains it just passes everything through ?

Ok try this, you should have separate group of users for each domain. I mean users on one domain beoolngs to 1 group.

Create 2 Connectors under Routing group.
Under general on one of them, use "use DNS to route to each address space on this connector." Then under Delivery restrictions "Accepted" and under "accepted message from" add the group that you want to allow to use this connector (@123.com)

Then on the other connector Under General "Forward All Emails to this connector to the fallowing smart host" then enter the server where you want to forward to. Then under Delivery restrictions "Accepted" and under "accepted message from" add the group that you want to allow to use this connector (@abc.com)

no garanteed, but you can try.

I have tried this ?. Not working

It seems that the filtering is not working at all, I have done the following reg hack as per Microsoft http://support.microsoft.com/default.aspx?scid=kb;en-us;Q277872 but no change.

When I setup the address space to * ,the rules don?t work , all mail is still passed through connector.

When I setup the address space to *abc.com with the rules it bypasses the connector and sends it to the exhange queue.

Try and just add you self in the allowed list then restart the connector. Try that. it may not like adding a group.
