Sure enough, it was the postfix configuration.  Thanks for suggesting it
Bill - I just put default Postfix (not Apple) times for wakeup on pickup,
qmgr and flush in the master.cf, Apple sets them to "-".  I had already
enabled pickup, which had things partially working, but missed qmgr and
flush.

Thanks for the assist!  I now happily have RT 3.8.1 running on Mac OS X 10.4
client.

In all reality, most services needed to make it all happen were in place,
but needed to be activated and slightly reconfigured.  None of it was too
difficult, but none of it was exactly 'out of the box' either...
