为什么SpamAssasin会因为RCVD_IN_PBL RBL而将电子邮件标记为垃圾邮件？

Question

我的电子邮件被SpamAssasin标记为垃圾邮件。问题是评分3.3 (除其他外)：

3.3 RCVD_IN_PBL RBL: Received via a relay in Spamhaus PBL
*      [212.95.7.48 listed in zen.spamhaus.org]

我和212.95.7.48没有任何关系。这个IP是从哪里来的？

Answer 1

通常，您需要检查SpamHaus以查看所报告的问题是什么：

http://cbl.abuseat.org/lookup.cgi?ip=212.95.7.48

IP Address 212.95.7.48 is listed in the CBL. It appears to be infected with a spam sending trojan or proxy.

It was last detected at 2012-10-21 09:00 GMT (+/- 30 minutes), approximately 1 days, 7 hours, 59 minutes ago.

It has been relisted following a previous removal at 2011-06-22 17:06 GMT (487 days, 23 hours, 52 minutes ago)

很有可能，这个节点上列出了一个被破坏的服务器，它在欺骗您发送垃圾邮件的地址。您可能有兴趣检查您的邮件服务器上的日志，以查看是否有来自主机的任何未发送邮件的失败响应。
