In this way, when we add more frontend machines (inevitable) and a loadbalancing system, we will have a good naming scheme, www2, www3 and so on.
And for the mailserver (mailinglists) e.g. mail.
Have you enought IP - Addresses to give the mail-service it's own? Then you can add an additional IP to one of the servers. If somethink goes wrong, only move the IP Address to get the service running on the other machine. You can also have a mailinglist service preinstalled on the second machine.
