hello, I may have asked this question before, but I never got it resolved and it pops back up every once in a while. The situation is: A long time ago... we had a server called EXCHANGE1 and everyone was on it. A year ago, we built a new server EXCHANGE2 and moved everyone to it, and decomissioned EXCHANGE1. However, NDR reports and such still say they are coming from postmaster@xxxxxxxxxxxxxxxxxxxx , how can I change this? Where is it done? I thought I read somewhere it was the "exchange administrator" account, but we have no such account. Thanks! Tony Anderson UW CSE Windows Systems Architect
