Make the SCL Value Available to Edge Transport Rules

Applies to: Exchange Server 2010

Topic Last Modified: 2011-03-19

You can use the Shell to make the spam confidence level (SCL) value on messages available for processing in transport rules that run on computers that have the Edge Transport server role installed.

Bb691082.Caution(en-us,EXCHG.140).gifCaution:
The following procedure stops and starts the Microsoft Exchange Transport service on the local Edge Transport server. Mail that flows through this Edge Transport server isn't delivered while the Microsoft Exchange Transport service is stopped.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Transport agents" entry in the Transport Permissions topic.

Bb691082.note(en-us,EXCHG.140).gifNote:
You can't use the EMC to modify the priority of the Content Filter agent.

This example sets the priority value of the Content Filter agent to 3. Because the Edge Rule agent by default uses priority value 3, its priority value is increased to 4.

  1. Use the Shell to set the priority value of the Content Filter agent to 3.
    Set-TransportAgent "Content Filter Agent" -Priority 3
    
  2. Stop the Microsoft Exchange Transport service.
    Net Stop MSExchangeTransport
    
  3. Start the Microsoft Exchange Transport service.
    Net Start MSExchangeTransport
    

For detailed syntax and parameter information, see Set-TransportAgent.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the "Transport agents" entry in the Transport Permissions topic.

Bb691082.note(en-us,EXCHG.140).gifNote:
You can't use the EMC to verify transport agent priority order.

You can verify the transport agent priority order by sending a test message through the Edge Transport server that you just configured. Then you can use the Get-TransportPipeline cmdlet to view the transport agent priority order. You must send a message through the Edge Transport server because the Get-TransportPipeline cmdlet retrieves information about the transport pipeline that's built dynamically every time a message is sent.

This example verifies the transport agent priority order.

  1. Send a message through the Edge Transport server that you just configured.
  2. Run the following command.
Get-TransportPipeline

The output produced by this procedure will resemble the following example. In the following example, the Content Filter agent is listed before the Edge Rule agent on the OnEndOfData SMTP event. This indicates that the Content Filter agent is now being applied to messages before the Edge Rule agent on the OnEndOfData SMTP event.
