I said about not setting default value into package but setting it
on a target host -- either using postfix's ability to list all
configured interfaces (on machine where it runs on, not where it
was built) or using package manager (dpkg in your case) ability
to execute script(s) at installation (again, on target machine)
time.

This will differ if you change your network setup (without recompiling!)
or run it on another host.

See above. By default, postfix uses information from machine it *runs*
on.

I build postfix as rpm (and many others does that too, using e.g.
vendor-supplied rpm), and there is *no* info from build machine
inside (except of rpm's "BuildHost" tag), and postfix installed
using that rpm package works on *target* machine using *that*
machine's configuration. Think of e.g. myhostname -- you don't
need to set it, postfix uses name of machine *it runs on* as
a default.
