Perhaps if I clarify my need...

NIC #1 DSL provider (static)
NIC #2 CABLE-MODEM provider (Static)

I need postfix to 'listen' on both. That seems straight forward enough.
However (during normal operation) I only want outbound email to use the DSL
provider...since the CABLE-MODEM IP is typically blacklisted and tough to
fix...the idea here is that if the DSL line fails, email can still come in
via the CABLE-MODEM... ideally it would be great if email could go out the
CABLE only if the DSL is down, but thats not really needed for now......

I just dont want day-to-day email using the CABLE for outbound..

So if I use 'smtp_bind_address' will this accomplish this?

Thanks-
