Catch-all domains are supported by GMail[1], and some registrars (example, namecheap [2]) will also forward all emails. Namecheap gives you 100 pre-defined mailboxes that can forward to different outgoing boxes, in addition to a catch-all.

For Gmail, it's only possible for paid accounts nowadays.

They took away the free "bring your own domain" around 13 or 14 years ago.

I never said it was free. Hosting your own server is also not free.

Just wanted to be clear, since self-hosting can be highly fiscally effective by utilizing internet and machines you already own. Cheers.
