I’ve been using Migadu for last couple years with no issues. All you need is a custom domain.

You can bring your own client, but there’s webmail too (requires no JS if I recall) so you can access your inbox from anywhere too.

Nice one, thanks for sharing!

Very underrated IMO. It has been a while since I last used it but I recall it was super light and snappy - even compared to other more well-known lightweight alternatives. It was definitely a pleasant experience. Happy to see it still going strong.

Sway and Gnome

The latter is mostly for other family members. But I like both.
