A Field Guide to the Fediverse

Wed, 12 Aug 2026 09:00:00 +0200

Old Reddit just started requiring a login.

Not new Reddit - old.reddit.com, the last corner of the site that still worked like a website instead of an engagement funnel.

That was the final straw for me, so let’s talk about the fediverse.

It’s the same instinct that’s had me running my own mail server and a media server for years - the fediverse is just the social layer of that habit.

What Is This Thing Actually

“Fediverse” is short for “federated universe.”

Self Hosted Mail Server

Wed, 08 Jan 2020 13:35:49 +0200

Here we go again, running our own services like a boss.I’ve tried out some mail server solutions namely docker-mailserver and citadel.

In the following I want to name and discuss features, set-up procedures and cons.

Citadel

Is easy to set up because it comes with its own installer, completely handling software installation and filesystem tasks for you.

It also has an interactive graphical installation walking you through the setup process, which makes this process even faster.
