I was wondering if anyone knew of a way to add a list of email addresses and domains to the list of messages filtered in Exchange 2000 System Manager. This is under the Filtering tab in Message Delivery Properties in Global Settings. I can add them one at a time but would like to add a huge list I have. Also, does anyone know if having thousands of addresses and domains in the filtering list will slow down my Exchange 2000 server. It’s a new server with lots of power.
