Hi

These are NDRs normally caused by virus infected computers, I think that it was netsky that did it. Basically the user sends an email pretending to be you. Thus when the exchange server picks up the email and sends it back, it just sends it back to where it thinks that it came from.

There isn't really a way of stopping them coming back to you unfortunately as far as I know

you can filter them if they come from the same domain all the time... and if you do not do business with these guys

Start Exchange System Manager: Click Start, point to All Programs, point to Microsoft Exchange, and then click System Manager.
 
In the console tree, expand Global Settings, right-click Message Delivery, and then click Properties.
 
In Message Delivery Properties, click the Recipient Filtering tab.

add the address.

Right click on your smtp virtual server, properties go to 1st tab under general, click advanced, click edit and then tick apply filter.

Restart your smtp virtual server and th messages will be filtered into your exchange server installation folder under filter folder.
