Performancewise, I consider (from the tests I ran for Conectiva back in 2000) qmail the second fastest non-commercial MTA. The fastests being exim. Commercial solutions like S/MAIL will beat them all to the ground, and S/MAIL is the basis of Exim just like QMail is the basis for Postfix.
Actually, postfix was written from scratch by Wietse Venema (developer of TCP Wrappers) and has nothing at all to do with Qmail. As a matter of fact, Dan and Wietse don't seem to enjoy good relations (Dan is a pain in the ass to deal with if you ask me). I wouldn't recommend qmail to anyone, and certainly not a beginner. Postfix comes with CentOS and will be a lot easier to integrate and maintain.
