The built-in default is:
$ postconf -d myorigin
myorigin = $myhostname
Looks like you've set "myorigin = $mydomain", with my $mydomain inferred
from the hostname by dropping the first FQDN label.

The aliases(5) table is only consulted when delivering mail to local
recipients (domain listed in $mydestination) via the local(8) delivery
agent. Alias expansion applies only to envelope recipient addresses,
and generally (absent an "owner-" alias) does not affect the envelope
sender or mail headers.
This may be a good time to clearly (re)state what problem you're trying
to solve, now that you're apparently able to assign the desired mydomain
to each machine.
