尽pipe所有的努力过滤垃圾邮件，即使我已经设置main.cf不允许它，并检查DNS等，我还是从未知的垃圾邮件。即使添加一个pcre：REJECT /.unknown./一些他们仍然通过，我不明白为什么！ 这是我的日志文件。 第一块是好的，它被拒绝了，这是从未知的。 第二块是相同的，从未知，但它通过，并没有被拒绝。 我希望拒绝所有的“连接来自未知”，不只是其中的一部分。 在Centos上的postfix v2.8.4。 任何想法我做错了什么？ 谢谢。
该块被拒绝

您正在查找reject_unknown_client_hostname 。
从文档 ：
reject_unknown_client_hostname （使用Postfix <2.3：reject_unknown_client）
当1）客户端IP地址 – >名称映射失败，2）名称 – >地址映射失败，或者3）名称 – >地址映射与客户端IP地址不匹配时，拒绝请求。 这是一个比reject_unknown_reverse_client_hostnamefunction更强的限制，它只在上面的条件1）下触发。 unknown_client_reject_code参数指定拒绝的请求的响应代码（默认值：450）。 如果地址 – >名称或名称 – >地址查找由于临时问题而失败，则答复总是450。
示例用法:(如在我的实时邮件服务器上所见）
smtpd_client_restrictions = permit_mynetworks, reject_unauth_pipelining, reject_unknown_client_hostname, permit
