Multiple IIS Virtual SMTP

Hi Experts,

We set up multiple IIS virtual smtp server with different IP and
domain. However, the emails go out always through primary IP of the
single NIC we have though we have multiple IPs. We have exactly the
same situation with this post:

I attempted to set up virtual PC with Win 2003 server as guest OS, it
works fine with NAT shared connection but set up a fixed IP in the
virtual machine make it cannot connect to the internet at all. Anyway
suggestion to have emails out with different outbound IP? Do we need
more NIC?
