Exchange 2010 Builtin Antispam Features & ORF RSS

1

Has anyone installed the builtin antispam feature of the Exchange 2010 along with ORF on the same server? We currently have Exchange 2010 (Mailbox, Client, Hub Transport) and ORF installed on the same box. I was wondering if there are any pitfalls of combining the two antispam measures? Thanks

@Mandeep Khalsa: We are not aware of any issues, but please consider that Exchange Content Filtering runs before ORF by default, so it may reject/divert emails before ORF could take a look at them. If you want ORF to filter first, follow the steps below:

1) Start the Exchange Management Shell
2) Enter the following command:

Get-TransportAgent | Format-List

3) As you will see, ORF has two agents, the "Vamsoft ORF Routing Agent" and the "Vamsoft ORF Receive Agent", the latter performs the filtering. The Content Filter Agent is called.... well, Content Filter Agent :) To change the priority of the filtering agent of ORF (e.g. to 4, to run before Content Filtering), run the following commands:

Set-TransportAgent -Identity "Vamsoft ORF Receive Agent" -Priority 4

4) Finally, restart the MSExchangeTransport Service to apply the changes:

Restart-Service MSExchangeTransport

Moreover, by assigning all tests to On Arrival and tagging blacklisted emails in ORF instead of rejecting them, you can create a custom rule in Exchange to elevate the SCL score of such tagged emails and redirect them to the Junk folder of the recipient for further review, see http://blog.vamsoft.com/2009/09/30/tales-from-tech-support-part-7-orf-and-scl-scoring/
