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 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?
