+/* 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
