Exim4 Install Prompt On Tailscale Install

Openhabian 3 on RPi4:

When installing Tailscale setup now prompts me to install Exim4. I don’t think it used to do this. Is there a reason this is being prompted for a Tailscale install?

Actually I guess I’m also curious what this does, if anything, that setting up an STMP server does not?

It has been doing that in a long time. I don’t recall the reason at the moment but there is one :slight_smile:

Exim IS an SMTP server but there’s many config variants so this is tailored to be compatible with other openHABian components. Read the code when you’re curious.
