I am looking to setup a email proxy server. The "scheme" I am using is;
Internet >> ASSP(proxy) >> Email Server
Email Server >>>> ASSP(proxy) >>> Internet
I am wanting to use ASSP (http://sourceforge.net/apps/mediawiki/assp/index.php
ASSP and the Email server are on different severs so the port's shouldn't have an issue. What I am needing to know if possible is how to setup the email server to talk through the proxy server? What I have gather is with a "smarthost". Can you give me a step by step guide on this? If you are needing anything let me know.
