My business partner and I are both Mac users, but neither understands the reasons for running OS X server. Could you tell me: We have a domain name, and run our e-mail through that domain, maintained by a commercial company on a lease basis. Could we cut that cost by using OS X Server on our own machine (new Mini Server w/OSX 10.6, or OS X Leopard Server on a PPC G5 tower)? I assume we will still need an ISP contract, how does one access the internet when running OSX Server, same as for a regular OS X install? Sorry about the "basic" nature of these questions, we have little access to people that would know the answers. Thanks in advance for the help. Basically we want to know what can be done with OS X Server, will struggle with how to do it later.
