/etc/aliases is used only for mail handled by the local(8)
delivery agent.
Alternative: use a transport map; that works for all domains.
/etc/postfix/main.cf
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
[email protected] error:5.1.1 User does not receive mail.
Requires "postmap hash:/etc/postfix/transport".
