I have exchange 2010 running on Windows 2008 r2 and when an outside account sends email to an invalid address they are not getting a bounce back saying the account is invalid.  We have some former employees that we no longer support their email addresses and we want to make sure that clients get notified that their email was not delivered.  

How do I turn on the ability to send back an invalid user ndr?

In the Exchange Management Console go to:

Org Config> Hub Transport> Remote Domains> Default (Properties)> Message Format Tab - Tick Allow Non Delivery Reports.

Make sure you have some good spam filtering software enabled and using Recipient Filtering otherwise you will get blacklisted on Backscatterer.org

what happens when you test an unknown account from outside? If your server is seeing the email you should be able to track it. Please post what your server reports.

Awesome, thanks for the quick reply.  We have a fantastic spam service (spamsoap.com) but where do I setup recipient filtering?

Spamsoap needs to do this for you or you need to stop using them and bring Spam Filtering in house.

If they can't do it for you - you will get Blacklisted as spammers will send spam to you via spamsoap and your server will have to send back NDR's and as the spammers will forge the sender address, you will quickly hit a honeypot address (an address that has never been advertised except to be found by spammers) and if you hit one, you will immediately get blacklisted.
