You *can* do this, but probably should not. The problem is that your
forwarder will be saturated with spam that you will be poorly positioned
to process. Receiving systems will soon blacklist your forwarder, and
it becomes useless. Quaranine is not an option, and tagging will not
be acceptable to receiving sites. Your only choice is to have a very
effective filter to reject spam during SMTP, not easy to do.
