Following are the important consideration when we install Edge transport Server. Below mentioned points are to be strictly followed.

1. Edge Transport Should not be included in Active Directory
2. Should be installed in a Standalone Server
3. Edge Transport Should not be Part of the domain
4. ADAM Should be Installed

For installing Edge Transport Server, on the Installation type Page, Select custom installation to choose the Edge Transport Server Installation option

Select The Edge Transport Server Role, If you select the Edge Transport Server Role rest of the server Roles will be deselected because the Edge Transport Server has to installed in a Stand alone server without having any other roles combined to it

Protocols and Port setting

The following ports are opened through SCW

Port 25 – Should be opened both internally and externally, mails flow takes place with this port

Internal Port setting (Edge Transport Server to Hub Transport Server)

Port 50389 – LDAP local connection to ADAM in Edge Transport Server

Port 50686 – SLDAP (Secure Light weight Directory Access Protocol) Edge Sync Synchronization

Port 3389 – RDP optional

Edge Sync

Edge Sync – it’s a one way replication from Hub Transport Server to Edge Transport Server, while Edge Sync happens the recipient configuration will be replicated from Active Directory to ADAM in Edge Transport Server

In order to establish the Edge sync there are 3 important steps to be followed, the following options are done by exchange Management shell only

1. Create a Edge Subscription file from Edge Transport Server ( XML file)

New-EdgeSubscription –file “c:edge.xml, after entering this command it will ask for confirmation type “Y”

1. Move the file to Hub Transport Server – by using a pen drive or portable media.
2. Subscribe the file in Hub Transport Server

Navigate to Organization Configuration and in the action pane select New Edge Subscription and choose the path where the Edge file exists

Running Security Configuration wizard

1. Install SCW
2. Register SCW extension

Review all the setting and under Network security wizard open the following Ports

Port – 25

Port – 50389

Port – 50636

Edge Transport Server Important Points

1. Edge transport Server is not required for small organization; Hub Transport Server will function as Edge Transport Server

2. Edge Transport Server Role should not be a member of the Active Directory

3. ADAM stores the configuration of Active Directory for Edge Transport Server

4. Edge Synchronization to connect Hub Transport Server and Edge Transport Server

5. Security Configuration Wizard, Important ports to be opened, Port 25, 50389, 50636

Important Configuration for Edge Transport Server

1. Post Master Mailbox – create a New Post Master Mailbox which is used to receive the Non delivery reports, Postmaster can be in Edge Transport Server and also in Edge Transport Server

Post master mailbox can be created by Exchange management shell

To check for Postmaster Mailbox – (Get-TransportServer)

To create a Postmaster mailbox – (Set-TransportServer “server Name ” –Externalpostmaster Address ” Mail Address” After Creating a new email address for Postmaster and running the same command Get-Transport Server will shows the postmaster Mail Address

1. DNS Settings – DNS setting is the most important setting for internal and external mail flow

Internal DNS – Host record for the Edge transport server has to be created

External DNS – MX Record pointing towards Edge Transport Server should be configured

Edge Transport Server Settings

With Edge Transport Server we can have the following configuration

1. Anti Spam / Anti Virus
2. Transport Rule, Accepted Domain and Email Address Policies
3. Address Rewriting

Address Rewriting

Address Rewriting Agent runs in Edge Transport Server. The main purpose of Edge Transport Server is to rewrite the Address the address to some other address. This plays an important role, consider if there are 5 Sub domain inside a forest and the entire sub domain want send mail outside with a unique address space.

Address rewriting can be achieved only with Exchange Management Shell

To know the Address Rewriting entries, (Get-AddressRewriteEntry)

To create a New Address Rewrite Entry,

New-AddressRrewriteEntry – Name ” Internal to External” – InternalAdress raj.syztalk.com – ExternalAddress Syztalk.com
