Are you sure you want to put NT machines on the firewall? Shouldn't there be UNIX machines there for better security?

We are looking at building a server that just does SMTP relay\filtering\scanning and put it in our DMZ. We are also looking at putting Trend virus scanning on the box so that our mail is scanned by two different AntiVirus companies before delivered to the users desktops. Our logic behind this is sometimes Trend comes out with a pattern a little quicker than Symantec, so we do both. We also do attachment filtering with Norton For Exchange. I guess I have a couple of questions about this; 1. What is everyone else using for SMTP relay. What software, location of server, etc. 2. What is the best SMTP relay software\hardware? Should I just use another install of Exchange on a regular server`? Any suggestions or relevant web sites will be greatly appreciated.
