new Exchange 2010 setup

I am setting up a new Exchange 2010 environment. Here is what I have:

One Active Directory domain with 300 users
Two separate external email domains.
50 users are adb.com domain, and the other 250 users are xyz.com domain
The adc.com domain must use a smart host to send mail through.

I wanted to setup one mailbox server for the first company and one mailbox server for the second. Then use one HUB and CAS server for both companies. I have discovered that I cannot setup separate send connectors in Exchange 2010 without third party software.

So….do I buy the third party software, or change my design?

One MB/HUB/CAS server for each company
One MB server for each company and one HUB / CAS server for each company

Exchange OUTBOUND routing is recipient based and NOT sender based so you are correct that you can not define multiple send connectors to handle this.

Why the NEED for the seperate smart host? Can you not relay ALL trafic through that smart host?

IF you must have your outbound split in two different directions then its either 2 exchange domain/servers or a third party product I am afraid.
