I've had good success installing spamass-milter-postfix from the EPEL 
repository, and then adding:

smtpd_milters = unix:/var/run/spamass-milter/postfix/sock

to /etc/postfix/main.cf, as instructed in 
/usr/share/doc/spamass-milter-postfix-0.3.2/README.Postfix

I don't have any amavis stuff configured.
