I have set up a new Exchange 2000 server to replace an aging machine, but since I didn't want any of the old troubles and stuff to be carreid across, I set up the new server basically identical to the old one. I only changed the Windows domain name to different one to avoid confusion. (I actually wanted to copy the files across, but had to resort to FTP to achieve this, since SBS doesn't allow to domains to co-exist). No mail is coming in and going out (I can see the queues) but users are not getting anything in their inboxes. There are three domains for which mail is accepted on the server and I cannot find any reason why this happens. Not even if I send a message to myself, do I get it back in my inbox. What do I do the troubleshoot this. Is there some form of message tracking like in 2003? All advice would be greatly appreciated. Thanks Roland
