=head1 NAME

policy-test - Postfix Policy Daemon Testing Tool

=head1 SYNOPSIS

B<policy-test> [I<options>...] unix:/file/path
B<policy-test> [I<options>...] inet:hostname:port

 -h, --help              display this help and exit
     --version           output version information and exit
 -v, --verbose           increase verbosity level

=head1 DESCRIPTION

policy-test is a script that converts Postfix log entries on the standard input
into requests to the Postfix policy daemon given as the first argument. It
can be used for:

=over 4

=item Testing the performance of a policy daemon

=item Pre-seeding a Greylist policy daemon with data from the logs

=back

Note that this program is still in its very early stages of development and
does only support a small subset of the normal attributes used in the Postfix
policy delegation protocol. It basically supports the bare minimum to make it
work with Postgrey.

Also note that a non-standard attribute is being generated: policy_test_time
contains the Unix timestamp of when the client connected.
