Ok. I think I've beat this subject to a bloody pulp, but, I have one last question about the hostname when initially installing Linux and how it affects ISPConfig. If, during the Fedora Core 4 setup, when it asks to "Set the hostname manually" for the hostname I use 'server.localhost', will this cause shortterm/longterm effects on the usability of ISPConfig? I will be hosting 4 domain names and I don't really want have an association to the server with any of them. Basically, I just want the IP address resolved to an error message and all 4 domain names to resolve the their appropriate folder. I can't think of any side affects doing this, but I don't know how all the ISPConfig interaction works and how the email server would react, if at all, having localhost defined initially as the domain name, and server as the host. I will probably have to use one of the domains for the Name Server, so, I'll have to bend the rule just a little in that case, but MySQL is already configured to run from the internal IP address, which is kind of what started me thinking about this. I was going to use the internal IP address, but it must have a name. Will 'localhost' work? Any input on this would be appreciated. Thanks.
