This version can't work, virtual alias recipients that don't rewrite to
a "real" domain aren't deliverable, even when there's a transport table
override. The only way to deliver these remotely as-is is to rewrite to
a non-virtual (alias) domain, and then rewrite again via an inverse
mapping in smtp_generic_maps.

This requires the domain to not be listed in virtual_alias_domains.
Just removing the domain from virtual_alias_domains should do the
trick.
