You need an explicit "mydestination =" (empty) for that. Is that the
case?

That should enable matching of unqualified (local part only) keys.

But with "mydestination" empty, local_recipient_maps is not pertinent.

You should set virtual_alias_domains explicitly to a list of your
desired virtual alias domains, or a separate table with same, unless
you really mean to have an empty list of virtual alias domains.
Do not rely on the obsolete backwards-compatibility setting:
$ postconf -d virtual_alias_domains
virtual_alias_domains = $virtual_alias_maps

No, not "empty", rather *default*.

The ambiguity is avoided by explicitly setting virtual_alias_domains
independently of virtual_alias_maps.

By setting an explicit list of virtual_alias_domains (empty if you
like).
