连接 yahoo mail 服务器需要AUTH,那么用户通过其他mail服务器向yahoo发信,也进行Auth吗?这不大可能 吧? 我的理解那儿不对? 谁能解释一下?

能 If you send mail to a yahoo account from anywhere (other mail server), it should be ok; but it may do the reverse dns lookup. I am not sure how the yahoo mail server works, but this could be a reason. If you want to send mail to other place thru yahoo smtp server, it may not go thru, because most of smtp server have very restricted relay policies. Unless your server/domain is on their allow-list, it usually drops the relay message.
