You need a recipient ACL that looks something like this:
accept
set acl_m_last_rcpt = $local_part
domains = +local_domains
# reject if tests below "endpass" fail
endpass
message = unknown user
# here we do a callforward to see if we can deliver to the recipient
verify = recipient/defer_ok/callout=600s
