Best practice on Exch2010 NDRs

Im doing some testing on Exch2010 as prep for our migration project, but Im still not that expirienced..
One thing I can quite find, is how to get rid of the NDRs that are send as result of spam..they are filling up my queues..
I found articles stating just to disable them entirely, and others stating that doing that will get me blacklisted...and then again others saying that I should enable reciepient filtering instead..
The last one sounds like the proper solution, but seem its only an option to set on a edge server, which I dont have in this single server setup..

Any advice on this ?

Thx in advance

Although the RFC is to keep NDR however current practice, and due the that spam issues you are facing, is to completely disable NDRs.

Disabling them won't get you blacklisted and it is currently the recommended approach
please read this article http://www.vamsoft.com/howto-stop-backscatter.asp it explains it better than I do

Another option is to enable recipient filtering by installing anti spam on the hub transport server if you don't have edge

The proper solution is to install the anti-spam components on your Hub Transport server, then enable recipient filtering. You do not need an Edge server to install these components.

Fire up Exchange Management Shell, navigate to the C:\Program Files\Microsoft\Exchange Server\V14\Scripts directory and execute the command '.\install-AntiSpamAgents.ps1'. Then restart the Microsoft Exchange Transport Service and a new tab (Anti-Spam) will appear in Organization Configuration > Hub Transport. Use this to enable and manage the spam filter settings.

I do disagree with the point about disabling them. The NDRs are not a nuisance if you can properly control them. The RFC says to enable them for a reason - in a legitimate case of an email not being delivered, the NDR will notify the user there was a problem and gives the Administrator material to begin the troubleshooting process. If you enable Recipient Filtering, you will stop the backscatter issue.
