Anyone can implement it in postfix. Just use:

If you are using a version so old that it doesn't support postscreen,
then Wietse isn't your friend.
Note that even for people using dangerously antique versions of Postfix,
the reject_rbl_client restriction directive (used in
smtpd_*_restrictions lists) also supports the specification of result
values.
