How to use an alternate SmartHost SMTP port in Exchange 2007 and Exchange 2010
How do I change SMTP port on a Exchange 2007 SmartHost?
How do I change SMTP port on a Exchange 2010 SmartHost?

Solution:

Follow the guide below to configure Microsoft Exchange 2007 or Microsoft Exchange 2010 SmartHost using a different port. In the example below port 587 is used.

This article already assumes your exchange system is able to send emails externally and therefore a Send Connector has already been created and configured correctly on the Hub Transport Server.

  1. Open Exchange Management Shell
    Start -> Programs -> Microsoft Exchange Server -> Exchange Management Shell
  2. Type the following

    Set-SendConnector -Identity "All Outbound" -port 587

    or the following if your connector is called something else from the default

    Set-SendConnector -Identity "SENDCONNECTORNAME" -port 587

Note

By Default the "Send Connector" is called "All Outbound" unless you have changed it or added additional connectors. To determine this you can type the following at the Exchange Management Shell

Get-SendConnector
