Adding E-mail Domain Used for Redirection to the List of Accepted Domains on Hub Transport Server

To add a new Accepted domain on a computer that has the Hub Transport server role installed, you can use either Exchange Management Console or Exchange Management Shell.

To add a domain to Accepted Domains list using Exchange Management Console

1. Run the Exchange Management Console and select the Organization Configuration | Hub Transport node.
2. In the Actions pane, click New Accepted Domain. This will start the New Accepted Domain wizard.
3. On the first page, provide the following information:
   • Name—Specify the accepted domain in the user interface, such as source.local (target.local).
   • Accepted Domain—Specify the SMTP namespace for which the Exchange organization will accept e-mail messages, such as *.source.local (*.target.local).
4. Select the Authoritative Domain. E-mail is delivered to a recipient in this Exchange organization option for the accepted domain type.
5. Click New.
6. On the Completion page, click Finish.

To add a domain to Accepted Domains list using Exchange Management Shell

Run the following command for the source Exchange organization:

new-AcceptedDomain -Name 'source.local' -DomainName '*.source.local' -DomainType 'Authoritative'

where *.source.local is the address space you want to use for mail redirection from the target to the source organization.

Run the following command the target Exchange organization:

new-AcceptedDomain -Name 'target.local' -DomainName '*.target.local' -DomainType 'Authoritative'

where *.target.local is the address space you want to use for mail redirection from the source to the target organization.

Establishing Internet Mail Flow through a Subscribed Edge Transport Server

The second option for establishing Internet mail flow between the target and the source Exchange organizations ( or between the source and the target Exchange organizations) is to subscribe the Edge Transport server to an Active Directory site. The connectors that establish mail flow to the Internet are created automatically when you subscribe an Edge Transport server to an Active Directory site by using the Edge Subscription process.

Before you begin this procedure, verify that the following prerequisites are met:

• Authoritative domains are configured on the Hub Transport server.
• E-mail address policies are configured on the Hub Transport server.
• Network communications over the secure LDAP port 50636/TCP are enabled through the firewall separating your perimeter network from the Exchange organization.

To establish mail flow to and from the Internet through a subscribed Edge Transport server, follow these steps:

1. Export the Edge Subscription file from the Edge Transport server.
2. Import the Edge Subscription file on the Hub Transport server.
3. Force EdgeSync synchronization to begin on the Hub Transport server.

Each step is explained in further detail in the related subtopics.

Export the Edge Subscription file from the Edge Transport Server

1. Run the following command on the Edge Transport server, providing the complete file path of the Edge Subscription file that you are creating. New-EdgeSubscription -FileName "C:\EdgeSubscriptionInfo.xml"
2. Copy the resulting XML file to the Hub Transport server.

Import the Edge Subscription file on the Hub Transport Server

On the Hub Transport server, run the following command:

New-EdgeSubscription -filename "C:\EdgeSubscriptionInfo.xml" -CreateInternetSendConnector $true -CreateInboundSendConnector $true -site "Site-Name"

Where Site-Name is the name of Active Directory site where the Hub Transport server is located.
