我的论坛最近被一系列类似的垃圾邮件轰炸。它们每次都使用不同的发件人、域名和 IP。（但它们总是关于某个建筑行业的会议。）
它们最终被归类到“拒绝”中，并带有 `Email::Receiver::BadDestinationAddress` 错误，系统会尝试向无效的发件人地址发送拒绝邮件。哎呀，日志太乱了。
事实上，它们根本没有 `to:` 或 `cc:` 地址。我了解到收件人实际上是在 SMTP 信封中定义的，而不是在邮件头中，并且邮件列表系统可能会故意省略 `to:`/`cc:` 字段。
我不太愿意深入研究 [Postfix 配置](https://meta.discourse.org/t/customize-direct-delivery-postfix-configuration/118759)，但显然它可以进行[邮件头检查](https://www.postfix.org/header_checks.5.html)…
想知道是否有人已经尝试过并有什么建议？
