Hi ,

I thought you are speaking about installing Anti spam agents in exchange 2013 .

Anti-Spam agents will be installed on mailbox servers.But the advisable method is to have the Anti-spam agents on the edge server which will placed on perimeter network to receive all the external smtp from the external world.So that forged connections will be terminated by the edge server itself.

Please have a look in to the following blog .

Hi Yasser

In Exchange 2013 we need to enable Anti-spam agents in the Mailbox servers since the transport categorization takes place on mailbox server.

 From Exchange 2013 SP1 we have edge servers in which we can enable the Anti-spam agents as well.

You can refer my blog for further info

I think you will find this video series helpful as it takes you through the installation and management of the anti-spam agents using the shell:
