After a configured period of time, the messages can be deleted.
Another protection available in the Content Filter agent is the ability to act on a safelist aggregation. This
feature collects safelists that Outlook or Outlook Web Access clients configure for users that can always
send to them regardless of the SCL rating of the message. The Content Filter agent takes this information
and makes it available on the Edge Transport server. The following cmdlets can be used to configure the
Content Filter agent:
??‘ Get-ContentFilterConfig
??‘ Set-ContentFilterConfig
??‘ Add-ContentFilterPhrase
??‘ Get-ContentFilterPhrase
??‘ Remove-ContentFilterPhrase
??‘ Update-SafeList
To configure the Content Filter agent, several steps are required:
1. First the Content Filter agent must be enabled on the Edge Transport server. Where multiple
Edge Transport servers exist, it must be configured separately on each. To enable the Content
Filter agent, run following:
Set-ContentFilterConfig -Enabled $True
2. By default, though, the Content Filter agent is enabled on the Edge Transport server for external
messages. It can, however, be enabled for internal messages also. This cannot be performed via
the Exchange Management Console. To enable content filtering for internal messages, run the
following:
Set-ContentFilterConfig -InternalMailEnabled $True
