/* 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.
