Best practice for managing NDR with Exchange 2007

Friday, June 5th, 2009


Basically what you should do is to enable the Recipient Filtering functionality to block emails addressed to invalid recipients.
In this manner emails will be rejected immediately without generating an NDR.
You can only do this if Exchange is receiving internet email directly.
If you have the Ex2007 Edge Transport go to:
Microsoft Exchange | Edge Transport | Anti-Spam
Otherwise for Ex2007 Hub Transport install the anti-spam agents:

Next go to:
Microsoft Exchange | Organization Configuration | Hub Transport | Anti-Spam
Open the properties for  Recipient Filtering and tick the checkbox:
‘Block messages sent to recipients not listed in the Global Address List’
