+/*++
+/* NAME
+/*	qmgr_enable
+/* SUMMARY
+/*	enable dead transports or sites
+/* SYNOPSIS
+/*	#include "qmgr.h"
+/*
+/*	void	qmgr_enable_queue(queue)
+/*	QMGR_QUEUE *queue;
+/*
+/*	QMGR_QUEUE *qmgr_enable_transport(transport)
+/*	QMGR_TRANSPORT *transport;
+/*
+/*	void	qmgr_enable_all(void)
+/* DESCRIPTION
+/*	This module purges dead in-core state information, effectively
+/*	re-enabling delivery.
+/*
+/*	qmgr_enable_queue() enables deliveries to the named dead site.
+/*	Empty queues are destroyed. The existed solely to indicate that
+/*	a site is dead.
+/*
+/*	qmgr_enable_transport() enables deliveries via the specified
+/*	transport, and calls qmgr_enable_queue() for each destination
+/*	on that transport.  Empty queues are destroyed.
+/*
+/*	qmgr_enable_all() enables all transports and queues.
+/*	See above for the side effects caused by doing this.
+/* BUGS
+/*	The side effects of calling this module can be quite dramatic.
+/* DIAGNOSTICS
+/*	Panic: consistency check failure. Fatal: out of memory.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
