How to enable Anti Spam features on Exchange Server 2013

In Exchange Server 2013 there are 2 roles now that are Mailbox and Client Access Server

The CAS in Exchange 2013 acts as a proxy only and does not do any data rendering or categorization. The message categorization happens on mailbox server now. So we need to enable Anti Spam agents on mailbox servers now.

Now Antispam feature is not enable to exchange Server by default. We need to run a script in Exchange Management Shell to enable the Anti spam.

Run this command using Exchange Management Shell

& $env:ExchangeInstallPath\Scripts\Install-AntiSpamAgents.ps1

This command will give you output as shown below

WARNING: Please exit Windows PowerShell to complete the installation.

Protocol Analysis Agent True 12

We need to restart the Mailbox transport Service on mailbox Server after running this command

The Content Filter agent, Sender ID agent, Sender Filter agent, and Protocol Analysis (sender reputation) agent should now be installed and running on the Mailbox server.

To verify this, run the following commands in the Exchange Management Shell on the Mailbox server.

Get-TransportAgent

To enable content filtering, run the following command:

Set-ContentFilterConfig -Enabled $true

To verify this has worked run following command in EMS

Get-ContentFilterConfig

Now we need to enable content filtering for internal messages.

Run this command to enable it.

Set-ContentFilterConfig -InternalMailEnabled $true

To verify if this has worked we need to run this command

Get-ContentFilterConfig | Format-List InternalMailEnabled

We can disable content filtering for single users and multiple users

Set-ContentFilterConfig –Bypassedsenders manu@rimtech.in

To verify this we need to run this command

Get-ContentFilterConfig | Format-List Bypassed*

So we have successfully enabled Anti Spam agents and content filtering on Exchange Server 2013 mailbox server.
