The unverified domains need an "" sign before the domain name. To
leave entire hierarchies in the table use a regexp table, or use
check_recipient_access instead of relay_recipient_maps to explicitly
allow/deny appropriate recipients:

        # Only given users valid in domain and all sub-domains.
        user1example.com DUNNO
        user2example.com DUNNO
        example.com 550 5.1.1 Invalid recipient
        .example.com 550 5.1.1 Invalid recipient

        # All localparts in domain, valid, but not sub-domains
        example.org DUNNO
        .example.org 550 5.1.1 Invalid recipient

        # Placeholder for future validation
        example.net DUNNO
        .example.net DUNNO

This assumes that "parent_domains_matches_subdomains" is empty (not
default, but highly recommended).
