Ok.  I am definitely making use of the zombie detection (pre-greeting, etc.), 
but I also use the DNSRBL’s on postscreen.  I was under the possibly mistaken 
impression that this was a bit more efficient instead of having a spam source 
connect, possibly negotiate STARTTLS and then start a SMTP transaction and then 
have it rejected based on smtpd restrictions.

Should I then continue to use postscreen for the zombie detection but then move 
my DNSRBL entries to smtpd restrictions ?

Apologies for belabouring the point - I’m just not understanding.
