Configuring the domains for which you'll
accept email. Your Exchange server will be
configured automatically to accept mail for
your forest root domain, but you might need to
configure it to accept mail from external SMTP
domains as well. For example, my network is
divided into two domains: production.com
and test.com. My Exchange server was configured by default to accept mail for production.
com, but my email comes through an external
domain, brienposey.com. I therefore had to
configure my Exchange server to accept mail
from this external domain.
To add a domain, navigate through the console tree to Organization Configuration\Hub
Transport. Click the Hub Transport container, click the Accepted Domains tab
in the detail pane, then click the New Accepted Domain link in the Actions pane
to add the domain to the list. As Figure 6 shows, you need to enter the domain's Fully Qualified Domain Name (FQDN) and
a display name. You must also specify whether the domain is authoritative, an
internal relay domain, or an external relay domain. Click New, and the domain
will be added to the list.
Subscribing the Edge Transport server. Setting up an Edge Subscription
is required only if your organization uses an Edge Transport server. An Edge
Subscription is basically a one-way trust with the Active Directory (AD) database
that lets the Edge Transport server receive AD information without compromising
the AD database in the process. First, you create an XML file on the Edge Transport
server by using the New-EdgeSubscription cmdlet. Then, copy the XML file to
your Hub Transport server. For security reasons, be sure to erase the file from
the Edge Transport server. Navigate through the console to Hub Transport, click
the Edge Subscription tab, then click the New Edge Subscription link in the
Actions pane. Now, click Browse to locate the XML file, verify that the Automatically
create a Send connector for this Edge Subscription check box is selected,
then click New to import the XML file and create the Edge Subscription. For
more detailed instructions for configuring an Edge Subscription, click the Subscribe
Edge Transport Server link in the list of post-installation configuration tasks.
Creating a Postmaster Mailbox. The last step in the configuration
process is to configure a mailbox to act as the postmaster. If there are other
Exchange servers in your organization, this step might not be necessary, but
you need to be sure. Open Exchange Management Shell and enter the following
command:
Get-TransportServer
Look at the ExternalPostmasterAddress column in the results and verify that
an address for the postmaster exists. If an address doesn't exist, you'll need
to specify a postmaster address by entering the following command:
Set-TransportServer -<server name> `
-ExternalPostmasterAddress `
<postmaster email address>
As you can see, this command requires you to
enter a server name and the email address for
the postmaster account. You can create a dedicated mailbox to act as a postmaster mailbox,
or you can send postmaster messages to a user
who already has a mailbox.
Finishing What You Start
As you can see, installing Exchange 2007 is only half the fun. You'll still
need to complete these important configuration tasks before you can use your
Exchange 2007 server. Keep in mind that your actual configuration tasks will
vary depending on your servers' roles and on your Exchange organization's existing
configuration. The post-installation tasks list in Exchange Management Console
should help you finish what you started and get your servers ready to run.
