Thank you, Ron For free, off the shelf, MTA my vote is Postfix. It performed very well for us handling hundreds of thousands of emails per day. It is very configurable, very secure, and pretty easy to use/configure. As dealing with email/spam configurations is pretty boring/annoying to me now-a-days I would recommend looking at commercial anti-spam service systems where you only need to change your MX record to use the service then do all of your configuring through a web GUI. That is of course assuming you have more than a $0 budget to work with. <gentle sales pitch> I work for a company that has a service like this and is written completely from the ground up in house and from scratch. Let me know if you're interested. </pitch>
