I'm not active these days, but waking up because this thread is getting out of
hands :-)

virtual means virtual domains, not virtual users:

That's not a valid rule for smtpd.conf, this syntax was that used pre-2018,
it should be rewritten as follows because actions and matching are now disjoint
concepts:
action "foobar" mbox virtual <catchall>
match for any action "foobar"

what you want is:
action "catchall" mbox virtual { "@" = username }
match from any for any action "catchall"
where username is the username of your local user that will catch all mails.
again, this is not virtual users as virtual does not mean what you think it
means here,
virtual users are handled through the `userbase` option to provide an alternate
userbase.
Note however that you should really add a catchall to domains, such as:
action "catchall" mbox virtual { "@poolp.org" = username }
or restrict the domains with an rcpt-to clause on the match rule:
match for rcpt-to { "@poolp.org" } action "catchall"
otherwise your MX will _seem_ to be an open-relay for some mailers since you're
going to
be accepting mail for any domain even though you won't be relaying them
afterwards. This
might still impact the reputation of your domain.
Cheers,
