Yes, and depending on the sieve implementation, we can make sure the
users (ourselves, in this case) don't override the rule and mess things up.

The first thing to do would be to change the documentation: instead of
using a ~/.forward file to forward your @g.o mail, you would use sieve:

  require ["copy"];
  redirect :copy "wherever@×××××××.org";

Then the global sieve file (run first) could do,

  require "fileinto";
  if header :contains "X-Spam-Flag" "YES" {
    fileinto "Junk";
    stop;
  }

which would stop processing, so that the "redirect" above never gets
executed.
