I am a little confused about the 'Relay Host' parameter. What exactly does ASSP 
do with this switch as far as its behavior is concerned?

I was using ASSP with very good success in front of an Exchange server which 
uses an ISP that requires a smarthost (port 25 outbound blocked). In that 
config it correctly proxy's my isp's smarthost for my exchange server.

Now I must configure another setup which doesn't use a smarthost (in that 
sense), so the Linux server that is running ASSP will have Postfix on it to 
route external mail. Looking at the flow diagrams, I believe to leverage all of 
ASSP's features, I will need the following:

Client -> Exchange -> ASSP -> Postfix -> internet
And
Internet -> ASSP -> Postfix -> Exchange
*or*
Internet -> ASSP -> Exchange

Postfix is listening on 10025, when I telnet to x.x.x.x:10025 I see the Postfix 
banner and when I telnet to x.x.x.x:25 I also see it (I recon this is correct).

I have the following configured:
Network Setup -> SMTP Listen Port -> 25
Network Setup -> SMTP Destination -> 127.0.0.1:10025
If I understand correctly, incoming mail will See ASSP and transfer to Postfix 
here which will route to my exchange server.

Relaying -> Relay Port -> 225
Exchange will connect here, and I will need ASSP to proxy back to Postfix. I 
guess I need
Relaying -> Relay Host -> 127.0.0.1:10025

If that's correct, am I also correct in guessing that whitelisting etc is 
performed based on the mail coming in through "Relay Port" and this is how it 
makes the distinction, versus ASSP handling mail in and out through one port?

Thanks!
