sendmail垃圾邮件的处理

lq2003

各位好，本人最近遇到sendmail服务器，前段时间为了能发送给msn邮件做了些处理，现在每天接收到较多的垃圾邮件，那位大侠有经验教教我该如何处理，在此先道谢！

获取的日志如下:

sendmail服务器的dns为10.10.10.9

上述内容中，toow@uniork.com.cn 邮件没有人为给enquiry@webtiful.com 发过邮件，是不是被攻击和利用了！在此谢谢！！

帮我看看  这个sendmail server存在哪些问题。

This server requires PTR for unauthenticated connections.

会不会是dns的问题,你的mail服务器的dns的反解记录是否正确?

lq2003

sendmail  可以不用本地的dns吗？

不明白你说的是什么意思.

10.10.10.9是自己搭建的dns  server 。

mail server是一定要用自己搭建的dns吗？

chenyx

dns是必须的,并且你的域的邮件服务器的MX记录,A记录和PTR都要有.
至于是不是自己搭建的,没有关系,只要互联网上的能解析到就行

我这里应该是少一个 外网地址的反向解析  没有配置。
