The trouble is that mail is routed through a series of steps to figure
out where it goes, and only once its gone through those steps and
wound up for local delivery that aliases are looked at.

What's happening there is that mail without any domain is having
@$myorigin appended; postfix doesn't work with bare local addresses
(until it gets time for local delivery).  Not just from addresses, but
also to addresses.

So, your configuration will result in "Mail sjg" going to wherever
sjg@domain goes (MX lookup).  A bit like (IIRC) what sendmail's
MAILHUB configuration shorthand did.

There's nothing, until you tell it otherwise, to make 'root' special.

Not really, just a couple of lines.  Virtual aliases are applied more
in the way that you might expect sendmail to apply aliases, whereas
for postfix normal aliases only apply to local delivery.

It's a standard example configuration:

Look at the XCLIENT stuff for testing and simulating mail
conversations in various scenarios.
