How to block NDRs from Distribution Lists - Exchange 2003
I have stopped all users (except authenticated) from using a distribution list. Now I need to make sure that internet users do not get NDR reports from my SBS 2003 / Exchange 2003 server.
We are running Symantec Endpoint 12.1 for email as well, if that is of any help.
thanks,

Add a filter based on destination of the distribution list to have NDR captured.
Alternatively, add an Error-To: alternateaddress to distribution list outgoing emails.
Only from a particular distribution list on my exchange server.

Which way is the NDR ?
user a sending email to distribution list,
A recipient of the distribution list has email issues such that their email server send an NDR back. Is this NDR that you do not want to be redistributed?

No. Internet user sends email. Only domain / authorized users allowed to send to distribution list. I do not want the outside user to know that that the message was refused.
Alternatively, add an Error-To: alternateaddress to distribution list outgoing emails.
