I've tried all sorts of combinations of myorigin, myhostname.
/etc/mailname and /etc/hostname :-) The ONLY thing that works is
changing /etc/hostname to the desired domain. The system behaves as if
it is straight-out ignoring any changes in main.cf. I had to introduce
errors just to convince myself it was actually being used.

Chris (who contacted me off-list so I will leave him/her anonymous
apart from their first name) very kindly sent me some working configs.
They did not help directly, but they DID lead me to read this again:
 
   http://www.postfix.org/ADDRESS_REWRITING_README.html#generic

... and that led me to read the man page for generic(5):

   http://www.postfix.org/generic.5.html

... and that led me to the idea that it should be possible to use an
entry something like this:

   @kt1.biplane.com.au @biplane.com.au

... to override the hostname with just the domain name.

However, I have not yet tested it.

Regards, K.
