ASSP (Anti-Spam SMTP Proxy) On CentOS 5.4 part 2

This is a follow up post to Fight Spam With #ASSP (Anti-Spam SMTP Proxy) On CentOS 5.4. If you haven’t already installed ASSP do so before continuing with this How To and remember that you need a working installation of Microsoft Exchange 2007 Server as well. This How To can be implemented on a live Microsoft Exchange 2007 server while it’s running. Leave the original ports (25 In and 25 Out, OWA and/or internal usage ports) alone and create new ones. Once you’re ready to go simply activate the new ports, then deactivate the original ports, your users will never see a glitch in service and will make rolling back just as seamless.

Preliminary Note:

I am using a CentOS 5.4 i386 base installation with ASSP (Anti-Spam SMTP Proxy) and Microsoft Exchange 2007 Server already installed and configured in this tutorial.
