Great post!

I'm a rather dismayed to see those universities and institutes nowadays no longer as pioneers and innovators in this area, but instead as mere consumers of ready-made corporate solutions, following corporate interests and centralising solutions. I have two employers, both academic, and both have resorted to big-tech corporations that offer solutions like e-mail as a service.

Same here, my university recently switched from their Horde webmail to Exchange. The new outlook webmail is absolutely awful and I couldn't set up all the filters that I had before. Luckily I could enable IMAP login, thankfully without OAuth because imo that's another awful practice, so I can connect to it with non braindead mail clients. Still a massive downgrade and I bet they now have to run it on a 10x as powerful server because I hear Exchange is an absolute monster in terms of resource usage.

(Also, I've been self-hosting mail for probably 4 years at this point. Here's to many more!)

I like what you write, I am going to look deeper into it. It really sucks that the nearly utopian promises of the future and newfound freedoms have been progressively squashed. Every 'disruption' that looked like a return to that utopia has ultimately been evil and firmly entrenched in the capitalist mindset.

I am glad it is still possible. I think it would be healthy for me and everyone else to practice digital homesteading, to become self-sufficient while still being able to lean on the greater community of like minded people.

Aren't you afraid about some important email getting discarded without you knowing about it? Or about unnoticed downtime which results in missed mails?
