Jim,
Checking reverse dns before connect is only a first step in the battle
against UCE. I have seen lots of great postfix how-tos that explain numerous
ways to help you fight SPAM.
http://www.postfix.org/uce.html This will help with your Reverse DNS (look
for reject_unknown_client)
Also check out some of the other resource on the postfix.com homepage under
the UCE/Virus Section
