you can use several blacklists or header/body checks to block spam or  
malware to save your ressources. Another useful feature is the  
upcoming Postfix server "postscreen" - this feature will be available  
in Postfix 2.8.
Info: http://www.postfix.org/POSTSCREEN_README.html

Some header checks and maybe zen.spamhaus.org should block 85-95% of  
spam. All other messages can be scanned with  
spamassassin/amavisd/clamav or other commercial products.

To block malware you could also look at:
http://www.malwarepatrol.net/

Start with some good Postfix restrictions and then you can extend your  
setup with other filters/blacklists...
