description         Postfix policy server implementing greylisting
long_description    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 ago, \
                    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.

notes "
Postgrey will be running with following default parameters:
  user        : postgrey
  group       : postgrey
  tcp binding : localhost
  tcp port    : 60000

You will find configuration in ${prefix}/etc/postgrey
  postgrey.conf                         : launch options
  postgrey_whitelist_clients            : default clients whitelist
  postgrey_whitelist_clients.local      : customisable clients whitelist
  postgrey_whitelist_recipients         : customisable recipients whitelist
  postgrey_whitelist_recipients.default : default recipients whitelist (unused)

If you are using postfix, you should add to your main.cf a line:
  check_policy_service inet:127.0.0.1:60000
in the smtpd_recipient_restrictions configuration (after
reject_unauth_destination and other rules) and reload postfix daemon.
