%description
Postgrey is a Postfix policy server implementing greylisting. When a
request for delivery of a mail is received by Postfix via SMTP, the
triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first
time that this triplet is seen, or if the triplet was first seen less
than 5 minutes, then the mail gets rejected with a temporary error.
Hopefully spammers or viruses will not try again later, as it is
however required per RFC.

Edit your configuration files:
%{_sysconfdir}/main.cf:
  smtpd_recipient_restrictions = ...
    check_policy_service unix:postgrey/socket, ...
or if you like to use inet sockets (modify the IP if needed):
/etc/sysconfig/postgrey:
  OPTIONS="--inet=127.0.0.1:10023"
%{_sysconfdir}/main.cf:
  smtpd_recipient_restrictions = ...
    check_policy_service inet:127.0.0.1:10023, ...

%description -l pl.UTF-8
Postgrey to serwer polityki dla Postfiksa implementujący "szare
listy". Kiedy Postfix otrzymuje po SMTP żądanie dostarczenia poczty,
tworzony jest triplet IP_KLIENTA / NADAWCA / ADRESAT. Jeśli dany
triplet jest widziany po raz pierwszy lub był widziany po raz pierwszy
mniej niż 5 minut temu, poczta jest odrzucana z tymczasowym błędem.
Można mieć nadzieję, że spamerzy i wirusy nie będą próbować ponownie,
co jest jednak wymagane przez RFC.

Aby użyć tego programu należy zmodyfikować pliki konfiguracyjne:
%{_sysconfdir}/main.cf:
  smtpd_recipient_restrictions = ...
    check_policy_service unix:postgrey/socket, ...
lub jeśli chcemy używać gniazd inet (w razie potrzeby zmienić IP):
/etc/sysconfig/postgrey:
  OPTIONS="--inet=127.0.0.1:10023"
%{_sysconfdir}/main.cf:
  smtpd_recipient_restrictions = ...
    check_policy_service inet:127.0.0.1:10023, ...
