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.
