昨天服务器系统日志里面显示大量的这种错误，这个错误是我的服务器有问题还是对方服务器的问题？
昨天是周日，我查了普通收发日志，量都不大，也都正常收发了。但是系统日志却有大量的这种错误日志，这是怎么回事呀？我是北京网通的，不会是昨天网通出问题了吧？

昨天晚上又出现了大量的进程，导致了我的邮件都没法发送，一发送邮件就弹出：Sorry, SMTP server too busy right now (100); try again later 的提示。
重启服务后又好了，估计是服务器给人做中继，发送了垃圾邮件了。
奇怪就在于我明明设置了禁止使用中继了，怎么还给人利用了，后来设置“动态屏蔽”，5分钟之内发送5封邮件就自动屏蔽30分钟，连续发送3次错误地址也屏蔽30分钟，才解决问题。
今天继续观察看看是否还有问题
