I am assuming that you are using Exchange 2000 You could try, Right clicking on the message delivery tab in the system manager and in the filter tab enter *@hotmail.com. Then right click on the smtp virtual service and chose properties, on the general tab click on the advanced button and edit the relevant ip address and then click on apply filter. This is a very simple way to block emails from exchange server it self.

The customer doesn't want to receive anything from any hotmail account. Under ADUC I can specify a "Accept Messages from everyone Except" and enter a recipient. However, this needs to be someone in the GAL. What I need to do is stop anything from *@hotmail.com from being received by the customer. I have looked at unauthOrig: which is the schema attribute for this but the format needs to be specified as a Distinguished Name. Does anyone have any bright ideas that I may try?
