+# Usage: greylist.pl [-v]
+#
+# Demo delegated Postfix SMTPD policy server. This server implements
+# greylisting. State is kept in a Berkeley DB database. Logging is
+# sent to syslogd.
+#
+# How it works: each time a Postfix SMTP server process is started
+# it connects to the policy service socket, and Postfix runs one
+# instance of this PERL script. By default, a Postfix SMTP server
+# process terminates after 100 seconds of idle time, or after serving
+# 100 clients. Thus, the cost of starting this PERL script is smoothed
+# out over time.
+#
+# To run this from /etc/postfix/master.cf:
+#
+# policy unix - n n - - spawn
+# user=nobody argv=/usr/bin/perl /usr/libexec/postfix/greylist.pl
+#
+# To use this from Postfix SMTPD, use in /etc/postfix/main.cf:
+#
+# smtpd_recipient_restrictions =
+# ...
+# reject_unauth_destination
+# check_policy_service unix:private/policy
+# ...
+#
+# NOTE: specify check_policy_service AFTER reject_unauth_destination
+# or else your system can become an open relay.
+#
+# To test this script by hand, execute:
+#
+# % perl greylist.pl
+#
+# Each query is a bunch of attributes. Order does not matter, and
+# the demo script uses only a few of all the attributes shown below:
+#
+# request=smtpd_access_policy
+# protocol_state=RCPT
+# protocol_name=SMTP
+# helo_name=some.domain.tld
+# queue_id=8045F2AB23
