Our IP is getting on a couple of block lists so I'd like to nail down SMTP
traffic to the SBS server only. I'm running a 2 NIC configuration so
fitlering at the router doesn't work. How can I configure SBS to only allow
SMTP traffic from the SBS itself and not the internal LAN?

Our IP is getting on a couple of block lists so I'd like to =
nail down SMTP=20
traffic to the SBS server only. I'm running a 2 NIC =
configuration so=20
fitlering at the router doesn't work. How can I configure SBS =
to only allow=20
SMTP traffic from the SBS itself and not the internal LAN?
