Greg's right; you cn uyse the IIS SMTP essentially as a forwarder to the
internal Exch servers.
In turn, they fwd outbound through the SMTP service running on the ISA.

I'm thinking not... You can either use DNS to deliver mail directly to
the
SMTP host, or use a single smart-host in IIS. That's kind of a deal
breaker
for ISA to do it - but I agree that it should be a separate box for
that...
Let's not have our firewall doing domain-based SMTP delivery, eh? ;)
Oh, but, (duh) you can have multiple SMTP virtual servers, each with
their
own smart host. That's the ticket. But I wonder how the message
screener
would work with multiple SMTP virt servers... Never tried that. Jim?
Tom?
Bueller?

Yep..to the first part
AFAIK you can enter multiple remote domains in IIS. What i was also
thinking
was using the IIS SMTP service on the ISA box so i could use the message
screener. But i think i'd rather use dedicated mail relay if i had the
hardware, then i can do gateway spam and virus filtering.

I got ya... you're saying all SMTP traffic gets published from the ext
int
to the 3rd leg, and the 3rd leg will do domain based smart-host delivery
to
legs 1 and 2, which publish to the respective internal Exchange boxes...
In that private email, you were talking about the screener doing that,
but
the IIS SMTP service can only do single smart-host delivery, right?
What
did you have in mind for domain-based smart host delivery?

Thor
From what i get. he's got two network behind one ISA. Now i am assuming
that
this (the second network) is a new one. Otherwise, they must have thier
own
firewall and internet connection somewhere or he must have something
going
on serving up a gateway/firewall functionality to that network. Even if
that
is the case, the easiest way is put a third nic in the ISA box and
publish a
mail relay server.

Can you draw out the network? I'm confused on exactly how you've got
the 2
separate nets going... You have 2 clients sharing one ISA server?

3 NICs??
Why couldn't one use setup SMTP under IIS on ISA and have the Exchange
rule push the SMTP over to the ISA box and out through either network?

That's find but I have two networks with two different IPs. 192.168.x.x
and 10.10.x.x so how do I redirect the SMTP if the machine sits on one
network or the other?
