我似乎无法弄清楚为什么header_checks没有被评估。
我将以下行添加到/etc/postfix/main.cf：
header_checks = pcre:/etc/postfix/header_checks.pcre 这里是header_checks.pcre：
/^From: [email protected]/ REDIRECT [email protected]
为了testing它，我尝试了：
postmap -q "From: [email protected]" pcre:/etc/postfix/header_checks.pcre
这正确评估，并给我返回输出：
REDIRECT [email protected]
但是，当我收到来自[email protected]的电子邮件，这是行不通的。 我的maillog显示：

有任何想法吗？ 谢谢！
一个问题可能是在main.cf或master.cf中的某处有一个receive_override_options=no_header_body_checksclosures标题检查。 在master.cf文件中，它将是其中一个服务configuration条目中的-o选项。
receive_override_options有4个选项：
- no_unknown_recipient_checks不要尝试拒绝未知收件人（仅限SMTP服务器）。 这通常是在外部内容filter之后指定的。
- no_address_mappings禁用规范地址映射，虚拟别名映射扩展，地址伪装和自动密件抄送（密件抄送）收件人。 这通常在外部内容filter之前指定。
- no_header_body_checks禁用头文件/ body_checks。 这通常是在外部内容filter之后指定的。
- no_milters禁用Milter（邮件filter）应用程序。 这通常是在外部内容filter之后指定的。
no_address_mappings选项通常位于main.cf而其他选项则位于master.cf
“-o receive_override_options”将覆盖main.cf设置，以避免重复在内容filter之前完成的工作。 这些选项是对main.cf中指定的选项的补充

正如@HZC所说，它可能是一个-o receive_override_options问题。 我在这里有同样的问题： 我的问题，并解决了后postfix header_checks使用正则expression式适当的设置 。 我的情况是拒绝而不是DISCARD 。 如果您想作弊垃圾邮件发送者，您使用DISCARD，垃圾邮件发送者将不会收到任何通知。 欲了解更多关于这方面的信息，你可以访问这个链接 ，看看拒绝行动部分。
DISCARD结构：
DISCARD optional text... Claim successful delivery and silently discard the message. Log the optional text if specified, otherwise log a generic message.
