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?
