+/*++
+/* NAME
+/* postconf_service 3
+/* SUMMARY
+/* service-defined main.cf parameter name support
+/* SYNOPSIS
+/* #include <postconf.h>
+/*
+/* void pcf_register_service_parameters()
+/* DESCRIPTION
+/* Service-defined parameter names are created by appending
+/* postfix-defined suffixes to master.cf service names. All
+/* service-defined parameters have default values that are
+/* defined by a built-in parameter.
+/*
+/* pcf_register_service_parameters() adds the service-defined
+/* parameters to the global name space. This function must be
+/* called after the built-in parameters are added to the global
+/* name space, and after the master.cf file is read.
+/* DIAGNOSTICS
+/* Problems are reported to the standard error stream.
+/* LICENSE
+/* .ad
+/* .fi
+/* The Secure Mailer license must be distributed with this software.
