That sounds about right to me.  The main thing is getting routing
right so that list traffic addressed to oldserver gets routed to the
local Mailman instance.  I don't actually use Postfix virtual domains
so I can't assure you that a virtual domain is necessary or sufficient
to get your setup working, but it sounds like the right thing if I
understand the documentation correctly.
