NDR from Outlook rule?

Hi

We are running Exchange 2003 SP2 with Outlook 2003/2007 clients.

One of my users, userA, recieves unwanted email from spam@domain.com. The reason I notice this is because I see NDR's back to spam@domain.com in our Exchange queues. The problem is that the NDR's are being sent to an address that doesn't recieve mail, so we have the formation of mail loops. I'm curious to know how the NDR's are generated because her mail address is valid.

I have a couple of questions;

a) Is it possible for a user to set up a rule in Outlook or use another Outlook functionality (e.g. Blocked Senders list) to prevent a mail from being delivered to their mailbox and an NDR to be generated? I was under the impression the best they could do was move to Junk, since the fact that Outlook processes the mail indicates it has already passed through Exchange.

b) Are NDR's only generated at the Exchange level, i.e when a message cannot be delivered by Exchange to the reciepient?

c) Is there anyway for me to check -why- the NDR is being generated (e.g. the NDR code or the content of the NDR) using Exchange Message Tracking or any other Exchange based utility?

d) I did some checking and found out that the NDR's are being generated because UserA's mailbox is too full and has surpassed the policy limit. How can I prevent messages from spam@domain.com being sent to her address (and therefore being NDR'd back)? Is there a way in Exchange just to delete messages from a certain sender as opposed to blocking them with an NDR?

Hope someone can help!

* The below link could be helpful:

* And is that spam email is targetting only that users mailbox, you could also try changing that users email id (i.e. either adding some initials or something)

Good Luck (^_^)

* Ok the answers go as follows:

a) I guess if the client has processed a rule like "move in junk folder", the affected "email id" wouldn't get any notifications about it i.e NO NDR

b) Yes NDR's  are sent out by the Exchange server.

c) As far as my knowledge i guess the NDR code could be checked only in the recipients mailbox to whom the NDR is being sent. Otherwise you might think of using any packet sniffer kind of utility to monitor the smtp traffic going out of the network.

d) My previous comment should answer this query

Hopefully justified (^_^)
