Private Dev Project : Multisite / Multilanguage

Hi,

first and foremost: I am not a Pro. I started to develop my own private site on my local laptop and by doing so came across different Ideas what I could ad. It is very likely that I know how something, but also that I miss here and there some basics (In general: Learning by doing).

Objective :
A main site www.refugium.lan with the sub-portals. For example gardening.refugium.lan and cooking.refugium.lan, etc.. Gardening and cooking will be some sort of portals for such specific topics only. Lateron, when the first stable and acceptable version is fixed I will publish them on a public server with different domains, alike above but with valid TLDs and with a separate domain such as refugium.email.

Problem | Question :
How do I set up several local domains in a way that I can use them for bacula, webpage and email-addresses?

I found the Virtualhosts and hosts and hostname file, but I guess Apache won’t talk to bacula, postfix or dovecot, will it?

My environment:

Hardware :
Laptop : Lenovo
Model : N581
CPU : Intel Core i5-3210M @ 2.5 Ghz x 2
Ram : 8 GB
HDD: 1 TB

PS : For any questions of that kind ‘why bacula?’ it is easy. I want to have (later on) a simple setup, backup and restore solution for anything. This means I will end up with a live-system and a bacula-storave, also in case of server-failure, etc.
