mail.infoeng.flinders.edu.au    CNAME   adam.ist.flinders.edu.au
adam.ist.flinders.edu.au        A       129.96.1.21

It seems they are.

mark@ist.flinders.edu.au
  deliver to mark@ist.flinders.edu.au
  router = smarthost, transport = remote_smtp
  host adam.ist.flinders.edu.au [129.96.1.21] 

So does this mean that it is routing to adam directly, or via
"mail.infoeng"?  How can you tell?

The other thing I still don't understand, is how mail can be delivered
even though the exim daemon is not running (ie "/etc/init.d/exim stop"
has been run).  Because I tried this, and mail still seems to be
delivered outside.

Thanks,

Mark.
