Have you tried turning it off and on again?

I found this: https://forgefriends.org/blog/2023/06/21/2023-06-state-forge-federation/

Migadu is the best email hoster I know. I’ve been using them for all my emails during the last three years and never had an issue.

They allow catch-all recipients and forwarding, so your use-case should be possible.

Thank you, one more project I don’t have to do myself.
