Ehmmm.. why do you need to do that? :)

Anyway, something like this:

require "editheader";
require "variables";

# Take value from first header occurrence
if header :matches "X-Original-To" "*" {
     # delete existing headers to  prevent creating duplicate (optional)
     deleteheader "Delivered-To";

     # add the new header
     addheader "Delivered-To" "${1}";

     # delete old header (optional)
     deleteheader "X-Original-To";
}

Regards,

Stephan.
