Append the stuff below to the end of /etc/postfix/main.cf

#
# greylist + spam blocks

smtpd_recipient_restrictions =
     permit_mynetworks,
     reject_unauth_destination,
     reject_invalid_hostname,
     reject_unauth_pipelining,
     reject_non_fqdn_sender,
     reject_unknown_sender_domain,
     reject_non_fqdn_recipient,
     reject_unknown_recipient_domain,
     check_policy_service inet:127.0.0.1:2525
     permit

Then restart postfix.
