/* NAME
/* postconf_unused 3
/* SUMMARY
/* report unused parameters
/* SYNOPSIS
/* #include <postconf.h>
/*
/* void pcf_flag_unused_main_parameters()
/*
/* void pcf_flag_unused_master_parameters()
/* DESCRIPTION
/* These functions must be called after all parameter information
/* is initialized: built-ins, service-defined and user-defined.
/* In other words, don't call these functions with "postconf
/* -d" which ignores user-defined main.cf settings.
/*
/* pcf_flag_unused_main_parameters() reports unused "name=value"
/* entries in main.cf.
/*
/* pcf_flag_unused_master_parameters() reports unused "-o
/* name=value" entries in master.cf.
/* DIAGNOSTICS
/* Problems are reported to the standard error stream.
/* LICENSE
/* .ad
/* .fi
/* The Secure Mailer license must be distributed with this software.
