catch-all addresses just work with correct from address when replying

What do you mean by this? I’d like to be able to reply from a website@mydomain.com automatically.

For me Thunderbird makes me create an alias in order to reply to my catch all (*@mydomain.com). Did you have to configure something specifically?

I think they are using this: https://github.com/microsoft/terminal

It’s what I use on my Windows machines as well. It’s a huge improvement from the old CMD window.
