I'm trying to create two exchange servers in one single domain in production environment. We want to create a brand new exchange server to handle only traffic going to *@marketing.domain.com. We already have working exchange server 2010 deployed and just wanted to add one more exchange server to separate different traffics. Exchange1 = all traffics to *@domain.com Exchange2 = all traffic to *@marketing.domain.com Any idea where should I begin with? Is that easy to do? Thank you in advance for all inputs!!

Adam, Thanks for the quick reply!! IC!! So basicaly I will need to create a new AD Site and treat it like 1 domain, 2 sites, and 2 exchagne servers right? I already installed the Exchange2 ahread of time (Before posting). And now I will need to create a new AD sites under AD sites and services. Sicne I already installed Exchange2 already and what do I need to do to point the new Exchange2 to the new site? Thanks again for all your help! =)

Got it! Thanks!! I just found out from the dev team they are going to create custom transport agent and they do not need any email box or storage from the Exchange2. They want to have any email with *@Marketing*.domain.com to route to new Exchange2 server. Some example are 1234@Marketing1.domain.com 213@Marketing3.domain.com I'm thinking i will need to setup some kind of rules under Exchange1. Is that possible? Thanks!

I'm confused then, if they want it to route to Exchange2...yet Exchange2 will have no email boxes...where does the email end up going? Do they just want a dedicated HUB transport server to handle that mail while its being directed to its final destination? And if so, why?

Adam, turst me i'm confused from my dev people too! =) Anyway, now I'm back to the original question. I have new site up in different subnet. I also created another writable DC and GC on new site. Now I have Site A + Site B exchange server and trying to figure out how to setup new email box from Site B by using *@marketing.domain.com. When I was trying to create a new email box on Site B, I can only create under *@domain.com. Do I need to create a brand new sub domain just for that? Do I need to create a new "Send Connectors" under Hub Transport? Thanks again for your help!

Thanks again Adam!! One quick question, do you know is there any way we can create some kind of wildcard for the new email box? For example, I want people to email *@marketing.domain.comand all those email will go to email@marketing.domain.com mail box? Let me clarify what Im trying to accomplish. Our development team wanted to create a customize hub transporter to our live email server but we dont want them to do that. Thats why we created a brand new site and new exchange server and let them play with the new email server instead. I did a lot of research and found out there is no way they can create a customize hub transporter apply just on the new email server without touching the live email server since it must apply the customize hub transporter under the organization configuration. Their end goal is following: *@domain.com<~~ Live *@marketing.domain.com<~~ new server for the development team I have one mailbox already setup email@marketing.domain.com on the new server and the development want to have any email with *@marketing.domain.com(123@marketing.domain.comor 321@marketing.domain.comor anything@marketing.domain.com) to forward all the emails to one single email box.

Ok, I see. First, let me point out how bad an idea this is...accepting any email sent to that domain with no recipient filtering leaves you wide open to a DoS attack or anything really. Hello SPAM! ;) I would strongly strongly recommend you have your development team create specific email address that you back with specific mailboxes. That being said, if you want to proceed down this path...I think this is what you're looking for http://technet.microsoft.com/en-us/library/bb691132.aspx Take care adam

correct, you'll need an edge. Without that..I dont think its going to be possible...not 100% though, but I dont know how you would do it off the top of my head. I'll dig around some.
