尽管我已经尽力过滤垃圾邮件,但即使在我将main.cf设置为不允许它并检查DNS等之后,我仍然会收到来自未知的垃圾邮件.即使在添加了一个pcre：到REJECT /.unknown./之后他们仍然通过,我不明白为什么！这是我的日志文件.第一个块是好的,它被拒绝了,它来自未知.第二个块是相同的,来自未知但它通过而不被拒绝.我希望拒绝所有“来自未知的联系”而不仅仅是其中一些. Centos上的postfix v2.8.4.我有什么想法我做错了吗？谢谢.

原文链接：https://www.f2er.com/centos/373829.htmlreject_unknown_client_hostname.
从documentation开始：
reject_unknown_client_hostname (with Postfix < 2.3:
reject_unknown_client)
Reject the request when 1) the client IP
address->name mapping fails,2) the name->address mapping fails,or 3)
the name->address mapping does not match the client IP address. This
is a stronger restriction than the
reject_unknown_reverse_client_hostname feature,which triggers only
under condition 1) above. The unknown_client_reject_code parameter
specifies the response code for rejected requests (default: 450). The
reply is always 450 in case the address->name or name->address lookup
Failed due to a temporary problem.
