Every now and then I have an application that requires Postfix to be
installed. I assume this is because it wants to send email
notifications. I always get stuck at the point where you need to choose:
2. Internet Site
3. Internet with Smarthost
4. Satellite system
5. Local only
Try as I may, I have never found a simple site/document that explains
the basic differences between these items and when to use each of them.
The site I found simply tell you how to setup a specific option for a
specific application without really explaining why. So I just drop it
and always select "none", just to get it out of the way.
I think its time I get to know these items. Any one know of a good doc
site that give a nice overview and explains these selections. I would
like a nice overview and some examples. If you know of something,
please let me know.
My current application is a GitLab installation as a VM on a hosted
server. The VM is behind a NAT firewall and I connect to it via
OpenVPN. I have my email setup on Hetzner on my own domain.
