I'm setting up Mac OS X Server (10.5 Leopard) for the first time. I will be configuring it to run multiple domains (or "virtual hosts" as they are called), and for each domain I want to set up a Web site and e-mail. I bought the Mac OS X Server Essentials (2nd ed.) book to use as a reference.
Let's say I want to host two domains: example.com and anotherexample.com. Looking at page 319, it shows how to enable e-mail accounts for users in the Workgroup Manager application. Looking at the screenshot, it seems to imply that all users will need to be referencing the same mail server, which I am guessing is the initial server name that I use to set up Mac OS X Server. So, if I want to setup an example.com e-mail address for Alice and an anotherexample.com e-mail address for Bob, and they ask what settings they need to put into their e-mail clients, do I tell them both to use the server "mail.example.com" -- even though for Bob, that will look wierd, since he doesn't have an e-mail address on that domain?
If it's true that all users need to be using the same mail server, regardless of what e-mail address they have, should I set up the Server software with some kind of "generic" domain -- perhaps "examplehosting.com" -- so it doesn't "look" so strange?
