When I was in my first ISP job, a colleague spent some two or three weeks to create automation that would reproducibly create a mail server with postfix, dovecot, roundcube, and some amenities against spam and such.
Today I spent around two hours to create mostly the same setup using docker-mailserver and the roundcube container image. It’s rough around the edges but fully workable. MOST of the time was spent figuring out why my Hetzner VMs could not reach port 25 of remote peers.

It felt really good to make this. At times like this you can really feel that we have made some progress. For all the new complexity of modern architecture, some building blocks have also managed to become extremely powerful. Maybe we can have a free internet one day despite all the corporate attempts to lock us into their platforms.
