• Using the Getting Started Tasks of the Windows Small Business Server 2011 Standard Console, to go Connect to the Internet => Configure a Smart Host for Internet e-mail
• • Select I need to configure a Smart Host for Internet e-mail.
  • Below Smart Host Server Information: enter the host name that we provided to you.
  • Check the My Internet Service Provider requires authentication box.
  • Below User name: enter the user name that we provided to you.
  • Below Password: enter the password that we provided to you.
  • Select Next

We recommend that you configure your system to connect to our Smart Host on port 587 with TLS (STARTTLS) encryption.

• To verify that you have TLS enabled, open Exchange system manager and go to Organization configuration => Hub transport => properties of the Windows SBS Internet Send connector => Network => Click Change... There you can configure your authentication and make sure that TLS is enabled (selected).
• To set the port to 587, open Exchange Management Shell
  and start by checking your Send Connector(s) :

      Get-SendConnector

  You should get the name of your send connector(s) – like “Default Send Connector”. If you haven’t changed the port configuration of the connector yet, it should be using the default port -25. It is a good idea to confirm this with the command:

      Get-SendConnector | fl port

  Then change the port with the command:

      Set-SendConnector –Identity “Your Send Connector Name” -Port 587

  If you have only one Send Connector you can use that command too:

      Get-SendConnector | Set-SendConnector -Port 587

  Of course, it is a good idea to check the final result again with:

      Get-SendConnector | fl port

  Or even take a look at the full listing for the send connector:

      Get-SendConnector | fl
