Quoting W B Hacker: > ... domain ... > ...servers, services, or whatever. > Where is the 'virtual'?
Thinking of the historical meaning of a domain, where hosts in a network are something like host.section.example.net, a mail-/web-/$anyservice-server handling (*.)example.net (and probably other domains) does not really contain contain the whole domain. I'd say it's more like a proxy (with some added functionality) or a wrapper. >From the outside, you don't know (and shouldn't care) if some.host.example.org is real or ... virtual, yes. Virtual doesn't mean that it doesn't exist. It just means there's something, but it may be something else than it looks like. The extra layer handling the virtuality makes its usage transparent. Think of virtual memory: You don't know which real memory location you are accessing, but you will surely access real memory (even if your data has to be swapped in before to the location). -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
