Just as a reminder, there is another similar program called smtpd,
available from www.obtuse.com, they have I think just released version 2.0
of the proxy. It has both anti-relaying and anti-spam support. I don't it
does filtering based on interfaces unless you use their own Juniper
firewall, but since there is already some support, it probably could be
hacked to understand between trusted and untrusted interfaces.
