you can. just don't set it to "void" (which means any address is valid).
If you don't need "local", then it's even better to avoid it at once:
local_recipient_maps = hash:$dir/empty
(where empty is an empty hash file) and use virtual aliases and/or
transports to implement the few "local" tasks that you need.
you may want to handle foo@[ip] addresses as they are considered local
however you set mydestination. you should accept mail to postmaster@[ip]
to allow people to contact you in case of serious problems, and possibly
reject all the rest.

just add a check_recipient_access to either reject or redirect to a spam
trap. Don't redirect to a spam trap if the address is still used to
opt-in in one or more marketing lists. spam traps must be protected
against misuse. We don't like some DNSBLs that rely on traps mostly
because of lack of trust in their trap protection.
