Postfix as a smarthost

Hello,

I'm setting up postfix to act as an SMTP Smarthost.

Basically, what I want to happen on the customer network is all traffic
on port 25 will get routed to this smarthost. From there I want
SpamAssassin to analyze/quarentine any infected messages. My question
is this.

Currently I have the box sitting with an internal address that has a
static NAT translation to an outside IP. There's no access list
blocking port 25, but I cannot get to the mail server on port 25
through that public IP

I've set up the proxy_interfaces properly, I believe. Is there any
tutorial's out there for setting up Postfix as a smarthost? Thanks!

This may not be a Postfix problem - it sounds like it might be an
IP/firewall issue. Does your ISP block external access to SMTP services on
your IP address range?

I've also given myself many headaches by forgetting to allow inbound
services in the host-based firewall. If you're running a host-based
firewall, are there any restrictions for SMTP in its ruleset?
