Milter-greylist

It seems that my question is a duplicate of a discussion on this list 
(mostly by Jim Klimov) in 2013.  I found that discusion at

   http://comments.gmane.org/gmane.mail.sendmail.milter.greylist/3315

It would be good if milter-greylist's sample greylist.conf file 
included examples which reduce "SPF spam" similar to thos posted in 
the above discusion thread.  Automatically whitelisting messages just 
because they passed a SPF test is not reliable any more since the 
spammers seem to have caught up by now.
