Spamassasin在我的电子邮件中给出以下标志：

*

0.8 RDNS_NONE Delivered to internal network by a host with no rDNS

“This test checks to see if there is a reverse DNS entry
for the last untrusted relay. Note that this may be done by
interpreting information in the relevant Received header – if reverse
DNS checks are not performed by the first trusted relay, or if they
are not recorded in the Received header, this test will be triggered
(regardless of the actual rDNS status).”

我能在电子邮件中看到的唯一IP是94.143.11.2 – >您可以将dns转换为trophymanager.com. Google和Hotmail对此没有任何问题 – 但Spamassassin给它一个标志 – 我在这里缺少什么？

解决方法:

不确定spamassassin,但许多邮件过滤器/ MTA(例如后缀)只接受rDNS条目,如果它是Forward-confirmed.在您的情况下,转发确认不起作用：

dig -x 94.143.11.2 +short
man01.trophymanager.com.

但man01.trophymanager.com没有A记录.

创建DNS记录：

man01.trophymanager.com A 94.143.11.2

和Spamassassin可能不会抱怨了.
