I’ve been using mailbox.org, and it’s pretty great. It’s cheap, it’s private, and it works well.
I like the idea of e2ee email, but the way they all work it’s pretty much a completely useless feature for most people, myself included, and I also like using Thunderbird. It’s just not worth the trade off for something I’d basically never get any use out of anyway.
This isn’t really an important point or anything, but I always find it odd when people bring up sysv init when talking about systemd. That’s kind of like arguing that people should switch to Linux because Windows Vista was bad. It’s not wrong, exactly, but it is a very weird thing to bring up in 2025.
