Hi. This is the qmail-send program at mail1704.wh.ocn.ne.jp.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
18.104.22.168 failed after I sent the message.
Remote host said: 451 Message temporarily deferred - 
I'm not going to try again; this message has been in the queue too long.
