Did this a while back. I used the basic sendmail+spamassassin setup that comes with FC4 and decided to move to Postfix because I wanted more powerful tools to fight spam.

If that is your only reason for changing, I'd recommend looking at sendmail+MimeDefang first (http://www.mimedefang.org/). MimeDefang runs via the milter interface and can do any kind of checks you want with the results available to sendmail during the SMTP conversation so you can reject at the smtp level instead of having to construct and return bounces. There is a fairly active mail list for support too.
