Stop right there. It's not qmail's job to act as a router, its the
network layer's job to route packets. Are the seperate routes to your
network advertised on the Internet so packets follow the best link in?

Remote MTAs will pick an IP without knowledge of which advertised IP
is the best IP to send data to given the network topology. Your scheme
won't result in traffic taking the best route in/out of your network,
though if you give both IPs the same MX preference inbound SMTP
connections may balance between your two links.
