I'm no postfix guru, but I think you may have to add to
the list in mydestination. mydestination is (I seem to recall) the list
of domains that will be treated as local ("deliver to this machine").

An alias will have no effect unless the email is given up for local
processing. The normal case is to look up the MX record for the
destination domain and ship the message out to the specified mail
exchanger... which seems to be what's happening to your test messages.
