You can't actually do this with Webmin, as the default configuration of Postfix
is determined by the Postfix package, not by Webmin. The alternative is to
write your own script that you run on the new system after installation that
configures Postfix or whatever to the setup you are looking for. 

You could use a script like :

#!/usr/bin/perl

use Webmin::API;
foreign_require("postfix", "postfix-lib.pl");
print postfix::get_current_value("mydestination"),"\n";
postfix::set_current_value("myorigin", "whatever.com");

This makes use of the Webmin::API perl module, which is a simple
wrapper that makes it easy to call Webmin API functions from your
own scripts. To get it, see :
