What does postfix need to be in a dmz zone?

[Josh Cason]

I have a dmz zone on my network. The postfix sits behind the dmz zone.  
The public IP address is translated (nat) to the dmz zone. I asked  
about the proxy interfaces command in the main.cf file. I was told I  
needed to put in the public ip address for the server. What does this  
do since it didn't seem to make any changes on my end regarding spam?  
I also disabled the src nat out on the firewall. My concern is stuff  
comming into the dmz zone. I'm currently watching the log to make sure  
all IP numbers show external. It seems like the some spam does not  
sport a ip number that postfix logs. As soon as I log the next attack  
or find a previous attack. I'll post the log.

Thanks,
Jsoh
