How to enable centralized mail transport powershell

To enable centralized mail transport using PowerShell, you'll need to configure the Send connector and the Receive connector on your Exchange Server or Edge Transport server. Here's a step-by-step guide:

Prerequisites:

  1. You have Exchange Server or Edge Transport server installed and configured.
  2. You have PowerShell 3 or later installed on your system.
  3. You have the Exchange Management Tools installed on your system.

Step 1: Connect to Exchange PowerShell

Open PowerShell as an administrator and run the following command to connect to Exchange:

$session = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://your_exchange_server_fqdn/powershell -Authentication Kerberos
Import-PSSession $session

Replace your_exchange_server_fqdn with the fully qualified domain name (FQDN) of your Exchange server.

Step 2: Enable the Send Connector

Create a new Send connector or modify an existing one to enable centralized mail transport:

New-SendConnector -Name "Centralized Mail Transport" -SourceTransportServers <your_exchange_server_fqdn> -SmartHosts <your_smtp_server_fqdn> -UseDomainSecureConnection $true

Replace <your_exchange_server_fqdn> with the FQDN of your Exchange server and <your_smtp_server_fqdn> with the FQDN of your SMTP server.

Step 3: Enable the Receive Connector

Create a new Receive connector or modify an existing one to enable centralized mail transport:

New-ReceiveConnector -Name "Centralized Mail Transport" -Bindings 0.0.0.0:25 -AuthMechanism <your_auth_mechanism> -Banner <your_banner>

Replace <your_auth_mechanism> with the authentication mechanism you want to use (e.g., BasicAuth, NTLM, or None) and <your_banner> with the banner message you want to display.

Step 4: Configure the Send and Receive Connectors

Configure the Send and Receive connectors to work together:

Set-SendConnector -Identity "Centralized Mail Transport" -ReceiveConnector "Centralized Mail Transport"

This command sets the Send connector to use the Receive connector for mail transport.

Step 5: Verify the Configuration

Verify that the Send and Receive connectors are configured correctly:

Get-SendConnector -Identity "Centralized Mail Transport" | fl
Get-ReceiveConnector -Identity "Centralized Mail Transport" | fl

These commands will display the configuration details for the Send and Receive connectors.

That's it! With these steps, you should now have centralized mail transport enabled using PowerShell.
