+/* NAME
+/*	qmgr_error 3
+/* SUMMARY
+/*	look up/create error/retry queue
+/* SYNOPSIS
+/*	#include "qmgr.h"
+/*
+/*	QMGR_TRANSPORT *qmgr_error_transport(service)
+/*	const char *service;
+/*
+/*	QMGR_QUEUE *qmgr_error_queue(service, dsn)
+/*	const char *service;
+/*	DSN	*dsn;
+/*
+/*	char	*qmgr_error_nexthop(dsn)
+/*	DSN	*dsn;
+/* DESCRIPTION
+/*	qmgr_error_transport() looks up the error transport for the
+/*	specified service. The result is null if the transport is
+/*	not available.
+/*
+/*	qmgr_error_queue() looks up an error queue for the specified
+/*	service and problem. The result is null if the queue is not
+/*	available.
+/*
+/*	qmgr_error_nexthop() computes the next-hop information for
+/*	the specified problem. The result must be passed to myfree().
+/*
+/*	Arguments:
+/* .IP dsn
+/*	See dsn(3).
+/* .IP service
+/*	One of MAIL_SERVICE_ERROR or MAIL_SERVICE_RETRY.
+/* DIAGNOSTICS
+/*	Panic: consistency check failure. Fatal: out of memory.
+/* LICENSE
+/* .ad
