If you want to avoid the MS processing overhead for these users, why not set
rules for "Spam Checks = " so that those users are listed as "no" and not
bother to do any spam checking for them at all?   Then just let the relay
machine deliver them as quickly as possible to the system which *can* do
proper address mapping to either dump the email to /dev/null or else return
"no such user".
