Looking for a email-provider where i can host my oen domain - Feddit

Not really about selfhosting, but I read that a lot of selfhosters do not selfhost their emails. Should have pop/imap. I am thinking about iCloud that offers 3 aliases, but actually I need 5. Does iCloud has a catchall-option? mailbox.org [http://mailbox.org] and skiff are „too expensive“ with 3€/month. migadu is another candidate. 19€/year. I once read about a cheap one-man-show-E-Mail-provider, that I would like to try, but I can‘t remember the name. Do you have more suggestions?
