Set up another instance of sendmail to handle incoming mail from the
gateway. Set up two IP addresses on that machine, and bind one instance of
sendmail to each. Then, use iptables to block incoming mail to the
"unscanned" instance of sendmail from any machine but your gateway. The
"unscanned" instance should drop mail into "mqueue" instead of "mqueue.in".
