I would like to remove my ip and dns info in the header from automatic responses from my Exchange 2007 to folks outside my domain.
E.G.
Delivery has failed to these recipients or distribution lists:
NoReply@yourserver.com
The recipient's e-mail address was not found in the recipient's e-mail system. Microsoft Exchange will not try to redeliver this message for you. Please check the e-mail address and try resending this message, or provide the following diagnostic text to your system administrator.

If you enable recipient filtering via the anti-spam filters then no one will see the information. In the current configuration you are causing backscatter which can get you blacklisted.

Removing the information isn't recommended - it can actually cause problems with the Exchange loop detection.

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Personally I would just leave it enabled and enable recipient filtering:
http://exchange.sembee.info/2010/hub/filter-unknown.asp

Having that information in an NDR does no harm - if someone wants to hack your network it will help them a little bit, probably save them about 30 seconds. Someone who knows what they are doing can get the relevant information another way.

You don't get security by obscurity.
