The default settings are:
address_verify_default_transport = $default_transport
address_verify_local_transport = $local_transport
address_verify_relay_transport = $relay_transport
address_verify_sender_dependent_default_transport_maps =
$sender_dependent_default_transport_maps
address_verify_transport_maps = $transport_maps
address_verify_virtual_transport = $virtual_transport
change at least:
address_verify_default_transport = discard
and any other settings would otherwise route verification probes to
external destinations.

This is setting does not do what you think it does. The RHS in
virtual_mailbox_maps is as mailbox pathname, not an email address. To
actually alias a recipient to an external address, use
virtual_alias_maps.
