/* 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
/* .fi
/* The Secure Mailer license must be distributed with this software.
