Creating a new SMTP email for domain users

Hi,

We have a single domain forest currently, but have purchased a new domain name to use for a subset of our company. We are running a Server 2008 Domain and Exchange 2007

My question is - do we need to create a child domain to enable some users to use this new email domain. Also, can we just use this new email address as thier primary, without having to append to the parent domain name?

for example

user@newdomain.com     instead of     user@newdomain.parentdomain.com

Thanks!

Jason,
     Each user will authenticate with the domain they are logged on to.  The email will go to their mailbox.  For example domain.com can accept email for domain.net and domain.org.  just make sure you have the correct mx records in dns pointing to your exchange server.

Thanks Richard.

Please clarify on the first question - do we need a child domain to host this new SMTP domain, or do we just created a new Accepted domain on the Hub server?

Thanks,

Jason

WINDOWS domains have nothing to do with EMAIL domains.
Therefore you don't need a child domain. You can just add the domain to the list of Accepted Domains then adjust the users as required.

Got it. Just making sure there no authentication or other requirement for an authoritative SMTP domain to be used.

Hi, Just a few follow up questions on this.

I added the new Authoritative Domain in Exchange, so we're not using a child domain.

Questions-

For the MX Record, should I create a new Forward Lookup Zone for the new SMTP domain and add an MX Record for the existing mail server? If I try to create an MX record for this new SMTP domain in the existing domain of our company, it tries to append the name like its a child domain. I created a new Forward Lookup Zone for the new SMTP domain, which allowed me to create the MX record correctly so I believe thats correct.

Also, do I need a Send Connector or anything else configured in the Exchange Console? I didnt see anything in the articles you references, but I want to be sure.

Thanks,

Jason
