The short answer is: set up a local DNS server with the apropriate MX entries to tell everyone's machine where to go for mail. Since you'll be configuring all the clients to talk to the mail server that has all the DNS info, nothing ever gets confused. Yes, you can do it. It's pretty easy (unless you're unfamiliar with DNS). Technically you _shouldn't_ just make up your own domain name, but if these machines will never touch the Internet, who's going to know or care. Just pick an apropriate name and use it. The only place you'll hit trouble is when you want to integrate the system into the Internet in a few years. -- Bill Moran Potential Technologies http://www.potentialtech.com
