It has some similarities; I use smtpd_helo_required,  
reject_invalid_hostname in smtpd_helo_restrictions, and  
reject_unauth_destination and reject_unknown_sender_domain in  
smtpd_recipient restrictions.  RBL checking is left up to  
SpamAssassin, and I use greylisting with a 180-second retry time and  
a 35-day expiry.  Some of the checks John mentions (such as MXen  
inside RFC1918 space) don't seem to catch much these days.

In SpamAssassin, I use all of the standard tests, with a well-fed  
Bayes db and slightly tweaked standard scoring.  A variety of RBLs  
are also checked.

A quick look through my mail logs shows that about 400 spams per day  
are hitting the list, so the current failure rate is of the order of  
1 in 2,000.

Yes, SA is regularly fed with my manually-filtered spam and ham folders.
